Question

Which of the following describes a covalent bond?

Answer 1

Answer:

It is the sharing of electrons between atoms with an electronegativity difference below 1.7.

Explanation:

Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.

It is the bond which is generally occurs within non metals as they share electrons to complete their octet.

The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .

Correct answer:- It is the sharing of electrons between atoms with an electronegativity difference below 1.7.

Answer 2

I think it is C, because a covalent bond is a distribution of 2 atoms to 1 electron, meaning they are sharing and not exchanging, and the electronegravity would be above 1.7
