A researcher has a sample of a radioactive substance. Suggest how she can determine whether the sample is emitting β\betaβ-particles and whether it is emitting γ\gammaγ-rays.
The table below lists properties of three main particles in an atom. Complete the table by identifying the missing relative charge and relative mass values.
| Particle | Relative Charge | Relative Mass |
|---|---|---|
| Proton | +1+1+1 | |
| Neutron | 111 | |
| Electron | −1-1−1 |
