Bond length is defined as the energy required to break a bond between two atoms.
B
A covalent bond involves the sharing of electron pairs between atoms.
C
An ionic bond is formed when electrons are transferred from one atom to another.
D

Verified step by step guidance1
Review the definition of bond length: Bond length is the average distance between the nuclei of two bonded atoms. It is a measure of distance, not energy.
Understand bond energy (or bond dissociation energy): This is the energy required to break a bond between two atoms, which is different from bond length.
Recall the nature of a covalent bond: It involves the sharing of electron pairs between atoms, which holds the atoms together.
Recall the nature of an ionic bond: It is formed when electrons are transferred from one atom to another, resulting in oppositely charged ions that attract each other.
Understand bond polarity: It refers to the unequal sharing of electrons in a covalent bond, leading to partial positive and negative charges on the atoms involved.
