Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R).$
→Assertion $(A) :$ Metallic character decreases and non-metallic character increases on moving from left to right in a period.
Reason $(R)$ $:$ It is due to increase in ionisation enthalpy and decrease in electron gain enthalpy, when one moves from left to right in a period.
