Practise labelling atomic diagrams and using tables of relative mass and charge for protons, neutrons and electrons.
Table 1 gives some information about three subatomic particles.
Complete Table 1 by giving the missing information.

Table 1
| Subatomic particle | Relative mass | Relative charge |
|---|---|---|
| electron | 0.0005 | -1 |
| proton | 1 | +1 |
| neutron | 1 | 0 |
Accept:
- minus one for -1
- one or +1 for proton relative mass
- zero / none / no charge for neutron relative charge
Reject:
- unqualified "-" for -1
Give the name of the part of the atom containing protons and neutrons.
