Web11 aug. 2024 · Some ions consist of groups of atoms covalently bonded together and have an overall electric charge. Because these ions contain more than one atom, they are called polyatomic ions. The Lewis structures, names and formulas of some polyatomic ions are found in Table 3.3.1. Table 4.3. 1: Some Polyatomic Ions WebAn ion is an atom or group of atoms with a positive or negative charge. Ions form when atoms lose or gain electrons to obtain a full outer shell: metal atoms lose electrons to …

WebThe melting point is affected by the ion’s size and charge density. The smaller the ion, the greater the charge density and the stronger the forces between the ions, which results in a higher melting point. As a result, KCl has a lower m.p. than NaCl. It is important to note that lithium salts do not follow this pattern.
