The elements of group II are known as alkaline earth metals. The electronic configuration of these elements . The electronic configuration of these elements is `ns^(2)` and oxidation state is `+2`. They have higher ionization energy than alkali metals in their respective period due to their small size and completely filled s-orbital. These elements give characteristic colour to bunsen flame. magnesium is used in the preparation of Grignard agent (RMgX) which is used in organic chemistry for preparation of sevaral organic compounds like alcohols. acids, hydrocarbons.
Q. The correct order of 1st ionization energy is

A

`Na lt Mg lt Al`

B

`Na lt Al lt Mg`

C

`Al lt Mg lt Na`

D

`Ag lt Na lt Mg`
