EasyWrite true or false for the statement: Electronic configuration of hydrogen resembles that of alkaline earth metals.
(FALSE) The statement is False.
Hydrogen has an electronic configuration of $1s^1$,which means it has one valence electron in its outermost shell.
Alkaline earth metals (Group $2$ elements) have a general valence shell electronic configuration of $ns^2$,meaning they have two valence electrons.
Hydrogen's configuration actually resembles that of alkali metals (Group $1$),which have a general valence shell configuration of $ns^1$.
