Resource summary

Flowchart nodes

  • Ions are charged particles 
  • When atoms gain/lose electrons, all they're trying to do is gain a full outer shell. 
  • Metals lose electrons to form positive ions
  • Non-metals gain electrons to form negative ions 
  • The number of electrons lost/gained is the same as the charge on the ion 
  • Group 1 and 2  elements are metals. 
  • They lose electrons  to form positive  ions
  • Cations 
  • Group 6 and 7 elements are non- metals
  • They gain electrons to form negative  ions
  • Anions 
  • Group 1 elements form  1+ ions, because they  have 1 electron in their outer shell
  • Group 2 elements form 2+ ions, because they have  2 electrons in their outer shell
  • Group 6 elements from 2-  ions 
  • Group 7 elements form  1- ions 
  • As you go down each group, you add electron shells, so the outer electrons get further from the nucleus   
  • As you do down, the outer electrons get further from the nucleus
  • For Groups 1 and 2, this  means it gets easier to remove the outer electrons so its more reactive as you go down the group
  • For Groups 6 and 7, it gets harder for the nucleus to attract extra electrons to form ions, so the elements get less reactive as you go down the group. 
  • When a metal and non metal react together, the metal loses electrons to form a positively charged ion and the non mental gain electrons to form a negatively charged ion 
  • These oppositely charged ions are then strongly attracted to one another by electrostatic forces and from an ionic bond 
  • They are held together by electrostatic froces
  • The oppositely charged particles have to BALANCE
  • You can show Ionic bonding using Dot and Cross Diagrams
