Question

A(n) _____ bond forms when two atoms share one or more pairs of electrons.

Answer 1

If electeon are shared, it is a covalent bond. The characteristic of covalent bond is that nonmetal elements share electrons to form stable compounds

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

When there is sharing of electrons between two atoms then it results in the formation of a covalent bond.

For example, carbon has atomic number 6 and its electronic distribution is 2, 4. Whereas oxygen atom has atomic number 8 and its electronic distribution is 2, 6.

Therefore, both carbon and oxygen atoms share their valence electrons in order to complete their octet and results into the formation of a coavlent compound $CO_{2}$.

On the other hand, an ionic bond is formed by transfer of electrons between the combining atoms.

Therefore, we can conclude that a covalent bond forms when two atoms share one or more pairs of electrons.
