Ionic character increases with the size of the cation as we move down the group.

Q. Metal hydrides are ionic, covalent or molecular in nature. Among $L i H$ , $N a H$ , $KH$ , $R b H$ , $C sH$ , the correct order of increasing ionic character is

$L i H > N a H > C sH > KH > R b H$

$L i H < N a H < KH < R b H < C sH$

$R b H > C sH > N a H > KH > L i H$

$N a H > C sH > R b H > L i H > KH$
