When carbon dioxide is formed, one carbon atom forms double covalent bonds with two oxygen atoms. Carbon dioxide is considered
A) less stable than the individual atoms because it is a gas.
B) less stable than the individual atoms because it can be decomposed readily.
C) more stable than individual atoms as now the outer energy levels of all atoms are filled.
D) more stable than the individual atoms because together they form a more massive substance.

Respuesta :

The correct option is "C", "more stable than individual atoms as now the outer energy levels of all atoms are filled".
 O::C::O
Any atom is stable or not, it depends on the filling of outer most shell with electrons whether or not their outer-most shell is filled with electrons. The atom is considered to be stable if atoms have their outer shell filled and if not, they are considered as unstable. To achieve stability atoms make bonds with other atoms.
