Discussion Forum
  • Since the size of the atoms is too tiny and we cannot compare their masses with conventional units, what unit do we use instead?
  • What is one relative atomic mass equal to?
  • Using this in q2, what mass of hydrogen is equal to carbon-12 atom?
  • What are the relative masses and charges of the sub-atomic particles in an atom?
