C2

• Ionic substances have high melting points due to there being a giant ionic lattice structure and strong electrostatic forces that require a lot of energy to break
• Ionic compounds can only conduct electricity when molten or dissolved due to there being ions that are free to move and carry a charge
• Ionic bonding happens between Metals and Non-metals
• In ionic bonding, metals lose their electrons and become a positive ion
• In ionic bonding, non-metals gain electrons and become a negative ion
• Ionic bonding is the transferring of electrons
• In covalent bonding, atoms share pairs of electrons
