Question

a. Arrange the following according to the instructions given in the brackets:
1. C1,
Li, F, N (Increasing order of electron affinity)
CI, S, AI, Na (Decreasing order of ionisation potential)

b. Down a group: Atomic size and metallic character ____while ionisation potential, electron
affinity & non-metallic character____ and nuclear charge____ (increases/decreases)​

Answer 1

Answer:

1) F>N>Li ( order of en)

Cl>Al>Na (across the period of ionisation energy decreases)

2) decreases, increases, decreases
