Question

In a covalent bond formation,

• A. transfer of electrons takes place
• B. equal sharing of electrons between two atoms takes place
• C. electrons are shared by one atom only
• D. electrons are donated by one atom and shared by both atoms

Answer 1

Answer: (B)

Formation of covalent bond:-
A covalent compound is made when two or more nonmetal atoms bond by sharing valence electrons. The shared valence electrons between two nonmetal atoms are called the covalent bond.
Covalent bonds are formed when two atoms begin sharing electrons, the electrons are attracted towards the nuclei that are positively charged. Example: $Cl-Cl$.
It is not necessary that both atoms of covalent bond always will be the same, they can be different for example HF molecule, in such case electrons not shared equally and attract towards the more electronegative element.
