# A student states that all atoms contain three types of subatomic particle. State the names of these three subatomic particles, give the relative charge of each one, and state where in the atom the majority of the mass is found.

> WJEC GCSE Physics (Wales) — 2.4 The atom, the nucleus and radioactivity · State · 4 marks

## Mark scheme (4 marks)

2. Neutron and electron named (both required for the mark)
3. Correct relative charges: proton +1, neutron 0, electron −1 (all three correct for the mark)
4. The majority of the mass is found in the nucleus
