Zinc ~ metals description

The chemistry of zinc is dominated by the +2 oxidation state. When compounds in this oxidation state are formed the outer shell s electrons are lost, which yields a bare zinc ion with the electronic configuration [Ar]3d 10. This allows for the formation of four covalent bonds by accepting four electron pairs and thus obeying the octet rule.
