Question

The total number of electrons shared between the atoms of a hydrogen chloride molecule is .

• A. 3
• B. 1
• C. 2
• D. 4

Answer 1

The correct option is C 2

Hydrogen has one electron and chlorine has seven electrons in the outermost shell. When they combine, they both share one electron each, i.e 1 pair of electrons, forming a hydrogen chloride molecule. So, one covalent bond, involving 2 electrons, exists in a hydrogen chloride molecule.
