Elements in the same column on the periodic table have similar chemical reactivity because: 

• They contain similar amounts of energy levels
• they have the same number of valence shell electrons
• atoms prefer to have completely full or completely empty valence shells
• they have similar numbers of isotopes

The noble gases, such as helium "He" and xenon "Xe", are non-reactive because:

• They have completely filled their outer electron shells
• they are chemically unstable
• they are unusually large atoms.
• they have been around longest on the Earth
