A) maximum in a period
B) minimum in a period
C) either minimum or maximum
D) constant
Correct Answer: A
Solution :
lonisation potential (IP) or ionisation energy (IE) of an element is defined as the amount of energy required to remove an electron from an isolated gaseous atom of that element resulting in the formation of positive ion. \[M\,(g)\xrightarrow{(IE)}{{M}^{+}}(g)+{{e}^{-}}\] In a period from left to right IP of element generally increases. The inert gas or noble gas has highest ionisation potential in their period because it is extremely difficult to remove electron from stable configuration. Note - Highest IP value element is He.You need to login to perform this action.
