Question

How will the tendency to gain electrons change as we go from left to right across a period? why?​

Answer 1

Explanation:

electron gain enthalpy increases as we go from left to right

coz it is directly proportional to Zeff and inversely to size

and on going from left to right in periodic table Zeff increases and size decreases

Answer 2

Answer:

Explanation:

Tendency to gain electrons increases from left

to right in a period because atomic size goes on

decreasing and effective nuclear charge increases.
