Web3 jul. 2024 · Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion . Ions are atoms or molecules which have gained or lost one or more valence electrons, giving the ion a net positive or negative charge. If the chemical species has more protons than electrons, it carries a net positive charge. WebTo find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound. In this video, we'll walk through this process for the ionic compound calcium bromide. Created by Sal Khan.

WebLithium Nitride: The only stable nitride of alkali metal is lithium nitride that has a very high melting point. In appearance, it is a red or purple-colored solid. It will release ammonia when it reacts with water. The crystal structure of this compound is unusual; that is, it has layers. Webin acetonitrile is lower than that in PC. The F‾ anion is much smaller than the Cl‾ and Br‾ ions; the lattice energy of LiF is smaller than LiCl and LiBr, it's more difficult for LiF to separate into cation and anion dissolving into polar solvents. The main factor affecting the solubility of LiF in a polar solvent is the dielectric constant.
