Ionization potential for a noble gas is

A.maximum in a period✓ Correct

B.minimum in a period

C.either minimum or maximum

D.constant

Explanation

Ionization energy is the amount of energy required to remove an electron from a neutral gaseous atom. Its trend increases from left to right in the period due to the decrease in atomic size. As noble gas is at the right of the periodic table, they have maximum ionization potential in a period and they have fully filled configuration. PERIODIC PROPERTIES 41
