Question

why electron gain enthalphy of O and F is less negative than that of the succeding element?? Plz answer faster​

Answer 1

Answer:

electron gain enthalphy of O and F is less negative than that of the succeding element because electron gain enthalphy increase on moving across a period and decreases on going down a group

increase in nuclear charge and decreases with atomic radius

Explanation:

Answer 2

Answer:

enthalapy increases

Explanation:

because electron gain enthalapy of o and F increases
