Answer 2

The compound in which a pair of electrons are shared between the atoms is Methane.

Detailed answer

The compound methane has a covalent bond so it shares electron pair between atoms

• Both lead bromide and sodium chloride do not share an electron pair between their atoms.
• This is because they are ionic compounds and only covalent compounds share their electron pair between other atoms.
• Methane is a covalent compound so it shares its atoms between electrons.
