• B. Two atoms attain stable inert gas electronic configuration by sharing one or more electrons.
• C. The shared pair of electrons is common property of both atoms.
• D. All of the above.

Answer 1

Answer: (B), (C)

The correct options are
B Two atoms attain stable inert gas electronic configuration by sharing one or more electrons.
C The shared pair of electrons is common property of both atoms.

The following factors favour the formation of covalent bond.
The combining elements should have comparable electronegativity.
Two atoms attain stable inert gas electronic configuration by sharing one or more electrons.
The shared pair of electrons is common property of both atoms.
