Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the most appropriate answer from the options given below :
| 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. |
Official answer
(3)
(A) is true but (R) is false.
