Question

define ionisation enthalpy and explain its group and periodic changes​

Answer 1

Answer:

ionization enthalpy is the energy required to remove an electron from a neutral atom. As we move from left to right in the periodic table the ionization enthalpy, in the same period, increases. And as we move from top to bottom in a group, the ionization enthalpy decreases

Answer 2

ionization enthalpy is the energy required to remove an electron from a neutral atom. As we move from left to right in the periodic table the ionization enthalpy, in the same period, increases. And as we move from top to bottom in a group, the ionization enthalpy decreases
