Question

explain on what character The ionisation potential depends
​

Answer 1

The ionization potential (IP) depends on atomic radius.

• IP increases as each electron is removed from the valance shell.
• More the electrons shielding of the outer electron, the less energy required to expel out an electron from the atom.
• As shielding effect increases from s to p to d to f (s<p<d<f) the ionization potential decreases.
