(a) They can lose electrons easily due to bigger size; energy required to remove electron is less.
(b) It is because of greater effective nuclear charge on Mg, i.e. more number of protons attract more number of electrons than Na.
(c) ‘F’ can form F– more easily than Cl due to smaller atomic size. F– is more stable than Cl–. Therefore, fluorine is more reactive than chlorine.
