Question

Relationship between Atomic size and Ionisation energy.​

Answer 1

Answer:

Explanation:

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

Ionisation Energy is inversely proportional to Atomic Size.
