Question

Answer for 1 chemistry (a) out of o & s which has more negative electron gain enthalpy & why? (b)how ionization enthalpy of atom vary in a period and in a group? How do you explain the variation?

Answer 1

Answer:

As we move down a group ionisation enthalpy decreases and it is because of the increase in nuclear charge .

In a period,ionisation enthalpy increases as a result of increase in nuclear charge and decrease in atomic size.
