Question

Explain the properties of f-block elements. ​

Answer 1

These elements have electrons, (1 to 14) in the f orbital, (0 to 1) in the d orbital of the penultimate energy level and in the outermost's orbital. There are two series in the f block corresponding to the filling up of 4f and 5f orbitals. The elements are 4f series of Ce to Lu and 5f series of Th to Lw.

Answer 2

Answer:

Properties of F block elements:

1. Have electrons added to the ‘f’ sub-orbitals of (n-2) level.

2. Are placed between (n-1)d and ns block elements in the periodic table.

3. Properties are similar to d-block elements.
