Question

What is ionisation enthalpy On what factors does it depend? How does ionisation enthalpy of the elements
vary as we move down a group and along a period?​

Answer 1

Answer:

Ionisation enthalpy is defined as the amount of energy required to remove one valence electron from an isolated neutral gaseous atom resulting in the formation of uni positive ion.

As we move down a group ionisation enthalpy goes on decreasing because the nuclear charge goes on increasing.

As we move across a period ionisation enthalpy increases because of the increase in nuclear charge and decrease in atomic size.
