Ions+Ionic bonding

• The number of protons is equal to the atomic number.
• An atom with an unpaired electron will be attracted by another atom that has an unpaired electron, resulting in ionic bonds forming between them.
• When atoms lose electrons they become positively charged ions (cations) and when atoms gain electrons they become negatively charged ions (anions).
• Atoms are more stable with a full outer shell of electrons
• An ion is a charged particle that has gained or lost electrons.
• Ionic compounds have regular structures (giant ionic lattices)

  in which there are strong electrostatic forces of attraction in all directions between oppositely charged ions.
• Metal - An element which loses electrons to form positive ions
• Non metal An element which gains electrons to form negative ions
• Ionic bond - A bond formed by the electrostatic attraction of oppositely charged ion
• Electrostatic - The force between a positive and negative charge.
