Nuclear equations

• In alpha decay a helium nucleus ( 2 protons 2 neutrons ) is emitted . The new element formed has :

  • A mass number that has increased by 4
  • An atomic number that has deceased by 2
• 0 should go in the _

  
• This is a alpha decay equation

  
• This is a alpha decay equation

  
• In beta decay the neutron turns into a proton and an electron is emitted. The new element formed has :

  • a mass number that stays the same
  • an atomic number that increases by 1
• This is a beta decay equation

  
• This is a beta decay equation

  
• In gamma decay there are no changes to the nucleus when gamma rays are emitted
