How to determine molecular or ionic
WebThe charge of a monoatomic ion (ion that consists of 1 type of atom) can tell you the oxidation state. For example, the oxidation state of copper in a copper (II) compound is +2. Mercury in the mercurous ion (Hg 2+2) is +1 (you have to divide the charge by 2 in this case). Nitrogen is -3 in the nitride ion, N -3 WebAug 14, 2024 · Based on the nature of the forces that hold the component atoms, molecules, or ions together, solids may be formally classified as ionic, molecular, covalent (network), or metallic. The variation in the relative strengths of these four types of interactions correlates nicely with their wide variation in properties.
