Question

Why is the electron affinity of Li more than B ?​

Answer 1

Answer:

$\underline{\huge{Answer:-}}$

In general, electron affinity increases across a period. ... The electron being added to lithium is going into the 2p shell which is relatively much closer to the nucleus (and has greater electrostatic attraction), while that going into boron enters the 2p shell, which is relatively more diffuse.

Answer 2

Answer:

In general, electron affinity increases across a period. ... The electron being added to lithium is going into the 2p shell which is relatively much closer to the nucleus (and has greater electrostatic attraction), while that going into boron enters the 2p shell, which is relatively more diffuse.
