(a)
Interpretation:
Reason for why alkali metals have high second ionization energy has to be explained.
Concept Introduction:
First ionization energy: The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.
Second ionization energy: The minimum energy needed to remove an electron from a unipositive gaseous ion to form a dipositive ion in the ground state is known as second ionization energy.
The outer electronic configuration of Alkali metals is
(b)
Interpretation:
Enthalpy of reaction per mole of
Concept Introduction:
The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.
