Ionic bonding

• • Ionic bonding is the reaction of a metal and non-metal
• • The metal atom loses electrons to form a positively charged ion
  • The non-metal atom gains electrons to form a negatively charged ion
• • The oppositely charged ions are strongly attracted by electrostatic forces
• • Group 1 and 2 metals are the most likely to form ions with a positive charge
  • Metals always lose electrons in ionic bonding
  • Group 6 and 7 non-metals are the most likely to form ions with a negative charge
  • Non-metals always gain electrons in ionic bonding
• • Dot and cross diagrams are used to show arrangement in ionic bonding
• • ionic bonding contains the transfer of electrons
