We humans, along with many other creatures, need oxygen in the air we breathe to stay alive.

How do you identify the group number and period of an element?

The number of valence electrons in the atom determines the group number of that atom i.e. if an element has 4 valence electrons then it must belong to group IV A. Since sodium has 3 shells, it belongs to period 3.

What happens if you inhale bromine?
