What are three differences between ionic bonds and covelant bonds?

Answer 1

Ionic bonds are formed between metal atoms and non-metal atoms. The metal atoms lose electrons and form positive ions, but the non-metal atoms gain electrons and form negative ions. Since the atoms both now have opposite charges, they are attracted to each other and form an ionic bond.

However, covelant bonds are formed between two or more non-metal atoms. The atoms share electrons rather than losing or gaining electrons from each other.

Answer 2

1. Ionic bonds form between atoms with significantly different electronegativities, resulting in the transfer of electrons from one atom to another, while covalent bonds form between atoms with similar electronegativities, resulting in the sharing of electrons.
2. Ionic bonds typically involve the attraction between positive and negative ions, leading to the formation of a crystal lattice structure, while covalent bonds result in the formation of discrete molecules.
3. Ionic bonds are usually stronger than covalent bonds due to the electrostatic attraction between opposite charges, while covalent bonds can vary in strength depending on the types of atoms and the nature of the shared electrons.
