formation of ions

• | ions

  • made when electrons are transferred
  • CHARGED particles
  • metals LOSE electrons to form POSITIVE ions
  • non-metals GAIN electrons to form NEGATIVE ions
• | forming ions

  • group 1 & 2 and 6 & 7 are likely to form ions
  • 1 & 2 are METALS: LOSE electrons to form POSITIVE IONS (cations)
  • 6 & 7 r NON-METALS: GAIN electrons to form NEGATIVE ions (anions)
• which groups are more likely to form an ionic bond?

  1, 2, 6 and 7
• what are ions

  charged particles
• when are ions made

  when electrons are transferred
• why do they transfer electrons

  to gain a full outer shall
• why do they try to get a full outer shell

  so they’re stable
• what happens when metals form ions

  LOSE electrons from their outer shell to form positive ions
• what happens when non metals form ions?

  GAIN electrons into their outer shell to form NEGATIVE ions
• what are positive ions also known as

  cations
• what are negative ions also known as

  anions
• group 1 & 2 are..

  metals
• group 6 & 7 are…

  non-metals
• metals … electrons

  lose
• non-metals … electrons

  gain
