Periodic Table of Elements
Inner transition metals are usually put at the bottom of the periodic table. These elements were sometimes called rare earth elements or rare earth metals due to their extremely low natural occurrence. They include elements (known as lanthanides) and (actinides). The lanthanides are very similar. The actinides are all radioactive. The period 7 inner transition metals (actinides) are thorium (Th), protactinium (Pa), uranium (U), neptunium (Np), plutonium (Pu), americium (Am), curium (Cm), berkelium (Bk), californium (Cf), einsteinium (Es), fermium (Fm), mendelevium (Md), nobelium (No), and lawrencium (Lr).

Transition metals are in the d-block and have valence electrons how to do alt symbols what is inner transition metals d-orbital's. They can form multiple oxidation states and form different ions. Iron, Cobalt and Nickel are ferromagnetic. Inner transition metals are in the f-block and trasition valence electrons in the f-orbital's.
They consist of the Lanthanides and the Actinides. The Actinides are radioactive and mostly synthetic. Let's continue talking about the periodic table and more specifically let's talk about the properties of transition and inner transition metals, so we call that transition metals are groups 3 through 12 and they're right in the mehals of the periodic table I'll point it out more materially and they have d orbitals and inner transition how to change your name by depol uk are located at the bottom of the periodic table and those guys have f orbitals.
Remember the d orbitals maximally hold 10 valence electrons and f orbitals hold a maximum of So all these guys both the transition metals and the inner transition metals exhibit properties of the other metals that ttansition see on the periodic table meaning they are good conductors of electricity, transitino have a nice luster quality to them and they're malleable which means they're soft and you kind of playable. Transitiion across a period in the transition metals and the inner transition metals, ttransition periods are the rows, so going across the row there is little variation in the what is inner transition metals size, in the electronegativity and in the ionization energy.
However, there are differences in the physical properties and so those differences in physical properties are determined by the electronic configurations of the various elements that fall within these two groups.
And so, when I say the electronic configurations I'm referring to the fact that if there are unpaired electrons, it causes the physical properties to be a mwtals bit different within the family. So the transition metals can also exhibit magnetic properties as a result of being able to have unpaired electrons, so if in the electron configuration you have paired electrons then we call that diamagnetic and if you actually have transitin electrons, then we say that that element or compound exhibits paramagnetic properties.
So iron, cobalt and nickel which are located here, here and here these guys are what we call ferromagnetic so they form permanent magnets so they're unpaired electrons kind of line up in a pole when they come in contact with the metald fields and they remain metala that formation which causes them to form a permanent magnet.
So just a little bit then about the inner transition metals which are the guys located at the bottom that have the two periods, period 6 the lanthanide series and period 7 the actinide series. So with the lanthanides, there is little variation in properties and in nature they're kind of all mixed together and so they're difficult to separate how to get from airport to hotel in venice we don't talk about them very much.
Then transitionn have the actinides which are the period sevens located at the very bottom of the periodic table and these are your radioactive elements and so only 3 of them actually exist in nature and the others are all synthetic and so the synthetic ones are starting here, uranium which is atomic number 92 and so we call those guys from uranium on to the end they're transuranium series and so those are all the iss with atomic number greater than 92 all the ones that have to be created in particle accelerators and things of that nature and that is more on the periodic table.

Uses of inner transition metals
Iron, Cobalt and Nickel are ferromagnetic. Inner transition metals are in the f-block and have valence electrons in the f-orbital's. They consist of the Lanthanides and the Actinides. The Actinides are radioactive and mostly synthetic. Sep 17, · Inner transition metals are chemical elements that are composed of valence electrons in their f orbitals of the penultimate electron shell.

The inner transition metals consist of two series of elements, i. There are various uses of inner transition metals in different industries. For instance, determining the age of fossils and making nuclear weapons. There are 14 elements in the actinoids series. Some of them include thorium, uranium, curium, nobelium, and fermium. The lanthanide series contains 14 elements, as well. Here are some of the examples; cerium, neodymium, promethium, thulium, and lutetium. In most cases, you will find them shown below other elements in the periodic table.
However, they generally belong to the sixth and seventh period. Lathanoid elements start from the atomic number These are elements starting from cerium up to lutetium. Contrary, the actinoid series consists of the metals that belong in between atomic number 90 to — I.
The incredible thing about these metals is that they were among the last to be discovered in the periodic table.
Besides, many of these metals do not exist naturally but are synthesized through nuclear reactions. They appear similar in terms of chemical reactions. Most lanthanoids are used to make sunglasses, strong magnets, and producing lasers. Amazing uses of inner transition metals. Most inner transition metals, such as Uranium, contain unique nuclear properties. Also, other inner transition metals such as plutonium can be used to make explosives.
However, Uranium is widely used because of its favorable properties and availability over the others. It contains 92 electrons, 92 protons, and six valence electrons. Its unique nuclear properties make it suitable for atomic weapons and nuclear power plants. Most inner transition metals are used to generate nuclear power. For example, nuclear power plants collide uranium atoms with neutrons. It helps in releasing uranium neutrons, which are hit with other particles later, forming a chain reaction.
Control rods manage the chain reaction while absorbing neutrons. The fission of uranium atoms inside the nuclear reactors releases energy. The hot water finally spins turbines to produce electricity. Some Lanthanoids are used to make lasers. They are formed when radiation is amplified by light. A laser converts optical or electrical energy into light. This energy is used to excite the molecules or atoms hence emitting monochromatic light.
Lasers consist of spherical or plane at the end containing laser material. Ordinary visible light is not coherent because it comprises of multiple wavelengths. Contrary, laser light contains only one wavelength hence making it different than the regular lights. Dating rocks, minerals, and fossils. Samarium and lutetium have long half-lives, which makes them suitable to date rocks and minerals.
These two metals have radioactive isotopes i. They are typically used to date rocks and minerals from the moon, meteorites, and the earth. Radioactive dating uses unstable elements that are always moving to form radioactive decay. Scientists and archaeologists use the inner transition metals to determine the age of fossils and other materials such as rocks.
Lanthanoids such as samarium, neodymium, and cerium can be used to make strong magnets when alloyed with other metals. Durable permanent alloy is created by the inner transitional metals by combining various metals with magnetic properties.
Examples of such metals include; nickel, Iron, and cobalt, which contain major magnetic elements. Any alloy for making strong magnets must contain one of these alloys.
One of the best alloy metal is Iron because it makes the material very attractive to the attraction. Harsh rays can damage our eyes due to radiation in the nonvisible and visible spectra. However, with the help of some inner transition metals, durable sunglasses are made. Although most of these sunglasses are plastics, the inner transition metals are used during the metallic oxidation stage.
They are responsible for absorbing and reflecting away light, which surpasses specific frequencies. Also, some sunglass frames are made from alloys made from mixing thee inner transition metals with other metals.
One of the most profitable uses of the inner transition metals is coating in electronic equipment. Thorium element is useful for tungsten wiring coating. Thorium fluoride is the most preferred material because of its low index and transparency from the U. Also, it has chemically stable and durable. Because it is a naturally radioactive material, it must be treated with a lot of care and disposed of accordingly.
It is prepared chemically following controlled steps and later melted under an inert atmosphere. Most inner transition metals do not exist naturally. They are produced in the labs or nuclear reactors for research purposes by scientists. Also, the inner transitional metals were recently added to the periodic table for educational purposes. They also contain some properties which are very rare to find in other metals.
Government organizations are also trying to maximize the potential of this element. Research institutes and nuclear reactors that produce the sell to other companies as raw materials. A wide variety of inner transition metals are super reactive. They are used to make armor and ammunition such as bullets, grenades, and missiles. Others are used to make bulletproof fiber vests and military shoes. Some of the most dangerous weapons in the world, including that atomic bombs, are made using such elements.
The nuclear bomb that was dropped on Hiroshima and Nagasaki was created by a highly reactive part known as plutonium. These elements are hazardous; hence, governments are strict on their production and usage. Apart from powering nuclear power plants, these metals are also used for medicinal purposes. For instance, Uranium is used to protect from radiation as a shield. Other elements are inserted into the body to act as tracers. Lastly, they also serve therapeutic purposes, such as destroying targeted cells in our bodies.
