Which of the following is the best explanation for a covalent bond?
Scrat [10]

Answer:

A. electrons simultaneously attracted by more than one nucleus

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 .

Thus, the electrons are attracted by the two different nucleus of the atoms that are taking part in the bonding.

<u>So, the correct answer is:- A. electrons simultaneously attracted by more than one nucleus</u>
