Question

Which elements have maximum and minimum
electron affinity in periodic table respectively?
(1) CI, Cs
(2) CI, He
(3) F, CI
(4) CI, Ne​

Answer 1

Answer:

1) Cs have max Cl have min

2)He have max Cl have min

3)F has max Cl have min

4)Ne have max Cl have min

Answer 2

Answer:

electron affinity depends on following factors

1. electron affinity ∝ Effective nuclear charge

2. electron affinity ∝  1/(atomic size)

3. electron affinity ∝  1/(screening effect)

4. electron affinity ∝ electro negativity

----------------------------------------------------------------------------------------

(1)

Maximum electro negativity - Cl

Minimum electro negativity = Cs

(2)

Maximum electro negativity - Cl

Minimum electro negativity = He

(3)

Maximum electro negativity - Cl

Minimum electro negativity = F

(4)

Maximum electro negativity - Cl

Minimum electro negativity = Ne
