Question

the tendency to gain an electron ________ on moving down a group of periodic table ? ​

Answer 1

Answer:

"On moving down a group, the tendency to gain electrons (electronegativity) decreases as the atomic radius increases due to the increase in number of shells. This increases the distance between the nucleus and outermost shell. This results in decrease in effective nuclear charge."

Answer 2

Answer:
