Which is an example of a covalent bond? There are fewer than 16 valence electrons in 2 chlorine atoms, but they form a stable bond. Chlorine accepts 1 electron from calcium to form a stable bond. Ions in a bar of pure iron are surrounded by a large number of valence electrons

Covalent bonding is a type of chemical bonding wherein there is a sharing of electrons to achieve chemical stability or the octet rule. For instance, the chlorine atom with one unpaired electron shares an electron to sodium to become stable. In the given examples, the situation that portrays covalent bonding is when Chlorine accepts 1 electron from calcium to form a stable bond.
