- 3What are isotopes?These are atoms of the same element with different numbers of neutrons (and hence different mass numbers).
- 4What are elements?An element is a substance that is made entirely from one type of atom.
- 5What does an atom's nucleus consist of?Protons and Neutrons
- 6What is the nucleus surrounded by?Electrons
- 7The nucleus of an atom is always...Positively Charged.
