Which of the statements describes a covalent bond ? Question 8 options:

none of the options are true.

The atoms in a bond vibrate around a distance where the internal energy is the highest.

Bond formation is favored by increased electron density between atoms and electrons delocalization.

The bond length and strength are determined by an increase internal energy.
