Question

Explain the difference in behaviour of first element of each group

Answer 1

Explanation:

The difference in the behaviour of the first member of a group in the s- and p-block compared to the other members in the same group can be due to the following factors: (i) Small atomic size of the first element. (iv) The absence of d-orbitals in the valence shell of the first element.
