What are the inner transition metals?
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).
Where are the inner transition metals?
f-block
Why they are called inner transition elements?
The “F-block elements” are called as the “inner-transition elements” because of their unique electronic configuration. The valence electrons of these elements transitions into the (n-2) f block which is the “anti-penultimate energy level” and lies in the f-orbital. Hence these are called as ‘inner transition elements’.
What are the characteristics of inner transition metals?
Main Characteristics of Inner Transition Elements
- In the inner transition elements the third last shell is filled with electrons.
- The inner transition elements form coloured ions.
- The inner transition elements show variable valencies.
- Actinides are radioactive by nature.
What are the characteristics of the transition elements?
Properties of transition elements include:
- have large charge/radius ratio;
- are hard and have high densities;
- have high melting and boiling points;
- form compounds which are often paramagnetic;
- show variable oxidation states;
- form coloured ions and compounds;
- form compounds with profound catalytic activity;
What is the difference between the inner and outer transition elements?
The main difference between transition metals and inner transition metals is that transition metal atoms have their valence electrons in the outermost d orbital whereas inner transition metal atoms have their valence electrons in the f orbital of the inner penultimate electron shell.
What are inner transition metals used for?
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.
What are the two periods of the inner transition metals?
The inner transition metals are divided into two groups: the period 6 lanthanide series and the period 7 actinide series as shown on your right.
Is calcium a transition metal?
Many scientists describe a “transition metal” as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table….Transition metal.

What is the difference between the transition metals and the inner transition metals?
What is the difference between the transition metals and the inner transition metals? Transition metals are elements whose final electron enters a d-sublevel. Inner transition metals are elements whose final electron enters an f-sublevel.
