Both alkali metals and alkaline earth metals are s - block elements. They resemble each other respect but still there are certain dismilariaties in their properties due to number of eletrons in the valence shell different atomic radii, ionisation enthalpy, electronegativity etc. The correct sequence of increasing covalent character is

1.	Both alkali metals and alkaline earth metals are s - block elements. They resemble each other respect but still there are certain dismilariaties in their properties due to number of eletrons in the valence shell different atomic radii, ionisation enthalpy, electronegativity etc. The correct sequence of increasing covalent character is
Answer» `BeCI_(2)ltNaCIltLiCI` `NaCIltLiCIltBeCI_(2)` `BeCI_(2)ltLiCIltNaCI` `LiCIltNaCIltBeCI_(2)` SOLUTION :As POLARISING power incrases covalent character INCREASES
