Question

The 2nd period element for example ‘F’ has less electron gain enthalpy than the third period

element of the same group for example ‘Cl’.Why?
​

Answer 1

Answer:

It is because of the less atomic size of F compared to Cl

Answer 2

It is because the less atomic size of F compared to Cl

Explanation:

The second period element 'F' has less electron Gain enthalpy than the third period element of the same Group for example 'Cl' because the electrons arranged in an orbit due to the inter electronic repulsive force acts and it prevent the entry of new coming electron.

hope its help uhh
