ionic compounds are electrically neutral overall. therefore, the sum of the charges on the cation and anion in each formula unit must be equal to zero
What is ionic compound ?
Ions are charged particles that form when an atom (or group of atoms) receives or loses an electron, and ionic compounds are composed of these charged particles. An anion is a negatively charged ion, whereas a cation is a positively charged ion.
- The simplest way to determine whether a chemical compound is an ionic compound is to see if it only contains two elements, one of which can be a metal (belonging to either of groups 1, 2, or 3), and the other of which can be a non-metal (from group 5, 6 or 7).
