प्रश्न
Give a reason for the following:
Ionisation potential increases across a period, from left to right.

उत्तर
The ionisation potential of an element increases across a period because the atomic size decreases as nuclear charge increases, and electrons in the outermost shell are more strongly held, requiring more energy to remove them.
