Ionic Bonding and Compounds

Question 1

definition of ionic bonding

Answer 1

transfer of electrons between a metal and non-metal. the oppositely charged ions are strongly attracted to each other by electrostatic attractions = ionic bonds

Question 2

how to work out the formula of an ionic compound

Answer 2

crossover method

Question 3

ionic compounds have …

Answer 3

• giant ionic lattice structures
• the ions are held together in a closely packed 3D lattice arrangement
• high melting and boiling points = lots of energy needed to overcome the strong electrostatic attraction
• only conduct electricity when melted or dissolved
