Question

How would tendency to gain electrons change as we go left to right across period?Why?

Answer 1

Answer:

Increases

Explanation:

Tendency to gain electrons increases and we go from left to right in a period because the effective nuclear charge increases and the atomic radius decreases

Answer 2

Answer: When we go left to right in a period the tendency to gain electrons increases.

Explanation: When we go left to right in a period the number of valence electrons(electrons in the last shell) increases in a series. The number of valence electrons is directly proportional to the nuclear attraction(the force with which electrons are attracted by nucleus towards it).High is the nuclear attraction , high will be the power of the element to gain electrons.

Thus, when we go left to right in a period the non-metallic character of elements increases.
