Question

What is electromagnetic affinity??​

Answer 1

• Explanation: In general, elements to the right of the Periodic Table have greater electron affinity than those to their left. ... Two groups of elements (2A and 8A) have no measurable electron affinity; they do not form stable negative ions at all.

Answer 2

Explanation:

Solution :

Factors effecting of electron affinity

1. Nuclear Charge : If nuclear charge increases electron afffinity increases , similarly it decreases if nuclear charge decreases.

2. Screening effect :If screening effect value increaes electron affinity increases of it decresaes electron affinity increases if it decreases .

3. Penetration power of the orbitals : If pentration power of the orbitals increases electron affinity increases . If it decreases electron affinity decreases.

4. Stable configuration : If an atomic has stable electron configuration electron effinity will decreases .

5 . Atomic radius : if atomic radius increases electrons affinity will be increases if atomic radius decreases electron affinity decreases .

6. Metallic property : If metallic property increases electron affinity decreases .

7. Non- metallic property :Non - metallic property increases electron affinity value increases.
