Group 0

Cards (7)

    • The elements in Group 0 of the Periodic Table are called the noble gases
  • They are unreactive and do not easily form molecules because their atoms have a arrangement of electrons( full outer electrons)
    • Noble gases are:
    • Non-metals
    • Monatomic (exist as single atoms)
    • Colourless and non-flammable gases at room temperature
    • noble gases have 8 electrons in their outer shell, except helium which has 2
    • Being chemically inert makes noble gases useful for many applications
    • The noble gases have very low melting and boiling points 
    • Going down the group melting and boiling point increases because:
    • The atoms get larger as you move down the group and their relative atomic mass increases
    • This leads to an increase in intermolecular forces between atoms
    • Therefore more energy is needed to overcome these
