Which type of bond involves the transfer of electrons between atoms?

Ionic bonding involves the transfer of electrons from one atom to another, leading to the formation of ions. In this type of bond, one atom donates one or more of its electrons, becoming positively charged, while the other atom accepts these electrons, becoming negatively charged. This transfer creates an electrostatic attraction between the oppositely charged ions, resulting in a strong ionic bond.

In contrast, covalent bonding involves the sharing of electrons between atoms rather than their transfer. Metallic bonding is characterized by a 'sea of electrons' that are shared among a lattice of metal atoms, allowing them to conduct electricity and heat. Hydrogen bonding is a specific type of attractive interaction between a hydrogen atom that is covalently bonded to a more electronegative atom and another electronegative atom.
