Ions are formed when electrons are transferred/lost/gained to achieve a full electron configuration and full outer shell.
Na-> Na+ +electron
Cl + electron-> Cl-
Group 1 and 2 loses electrons and forms: +1/+2 ions
Group 6 and 7 gains electrons and forms: -2/-1 ions
Compound ions are ions made up of groups of atoms with an overall charge. Examples of compound ions:
you only need to know ammonium, carbonate, hydroxide, nitrate, sulfate.
Ionic compounds have positive and negative ions, which are held with strong electrostatic forces in a lattice (regular) structure- This is ionic bonding.
e.g. Sodium chloride (NaCl) has Na+ and Cl- and the overall charge of the…
