Which of the following could be the subshell representation of an element of group iv? s2 s2pl s2p3 s2p2

for example, carbon has a configuration of 1s2 2s2 2p2  

so we take the latter two thirds of the configuration as that of the subshell - s2 p2

The correct answer is

Explanation:

The number of valence electrons that the elements belonging to Group IV contains are 4.

The electronic configuration for the elements belonging to group IV will be :

where, n is the number of period to which the element belongs.

Hence, the correct answer is

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
