pls answer the question​

Answer 1

Answer:

The amount of energy required to remove an electron from an isolated gaseous atom in the ground state is called ionization enthalpy. Ionization enthalpy increases along the period. ... Ionization enthalpy decreases down the group.

Answer 2

the amount of energy required to remove the electroni from an isolated gaseous atomi the ground state Is calledionsation enthalpy increses along the period

Explanation:

this is because along the period atomic size decrease and effective
