Ionic Bonding
1) Noble gases are unreactive and do not form compounds because they have the duplet or octet configuration (noble gas structure)
2) An ion is a charged particle. In an ion, the number of protons is different from the number of electrons (since the number of electrons are changed)
3) An atom forms an ion in order to chieve a noble gas structure.
4) Metals form positively charged ions (cautions). Non-metals usually form negatively charged ions (anions).
5) A polyatomic ion is a group of atoms that carries a charge.
6) Metals react with non-metals to form ionic bonds / ionic compounds / electrostatic bond.
7) Each ion in an ionic compound has the electronic configuration of a noble gas.
8) An ionic bond is defined as the electrostatic force of attraction between a positive ion and a negative ion.
9) An ionic bond is formed when electrons are transferred from a metallic atom to a non-metallic atom.
10) In an ionic compound, the total compound, the total positive charge is equal to the total negative charge.
11) An ionic compound consists of ions arranged in a giant ionic structure called a crystal lattice.
12) The physical properties of an ionic compound are as follows:

12) The physical properties of an ionic compound are as follows:
- Non-volatile, high melting point, high boiling point
- Usually soluble in water but insoluble in organic solvents
- Good electrical conductor in the molten state or in aqueous solution but not in the solid state
