उत्तर
A covalent molecule having a double bond between its atoms is oxygen.
Explanation:
An oxygen atom (atomic number 8) has 6 valence electrons and requires 2 more electrons to achieve a stable octet configuration. When two oxygen atoms combine, they mutually share two pairs of electrons between themselves. This sharing of two electron pairs results in the formation of a strong covalent double bond (O = O) within the (O2) molecule.
