Question

IE increase in period why​

Answer 1

This is Because

Moving left to right within a period or upward within a group, the first ionization energy generally increases.

As the atomic radius decreases, it becomes harder to remove an electron that is closer to a more positively charged nucleus.

They experience a weaker attraction to the positive charge of the nucleus.

Answer 2

Answer:

Size decreases and Effective nuclear charge increases along a period. More tightly the electrons are held by the nucleus, so more energy required to remove electrons. Thus I.E. increases along a period.
