      Hello!

      The average mass of one atom of lead is 207.2 relative atomic mass – that just means a single atom of lead is really quite heavy compared to other atoms like a hydrogen or carbon atom.

      At room temperature a cube of a centimetre weighs 11.3 gram, lead in liquid form weighs a little bit less!
