Question

What is the inner transition elmensg and why are they called s?

Answer 1

f- block elements are known as inner transition elements .

Answer 2

The f-block elements are only called the inner transition elements. The elements of the 6th and that of the 7th periods of Group 3 fall under this category. The series of elements that exhibit similar properties are lanthanides and actinides.

The major characteristics of the inner transition elements are:
1. They are heavy metals.

2. They have high melting point and high boiling point.

3. They show variable valencies.

4. They form coloured ions.

5. Some of them are radioactive in nature.

• They are named so because a series of these elements are kept in the one block in the periodic table.
