Formation of Ions

• Ion

  Charged atom/molecule
• How does an atom become an ion

  By losing or gaining one or more electrons
• When group 1 metals become ions, what charge will they have?

  +1
• When group 2 elements become ions, what charge will they have?

  +2
• When group 7 elements become ions, what charge will they have?

  -1
• When group 6 elements become ions, what charge will they have?

  -2
• Do group 0 become ions?

  No because they have a full outer shell of electrons so they don’t need to gain or lose electrons
