Table 11.1 gives information about the subatomic particles in an atom.
Table 11.1
| Name of particle | Relative mass | Relative charge |
|---|---|---|
| proton | 1 | |
| neutron | 0 | |
| electron | negligible |
Complete the table by writing the correct information in the three empty spaces.
State the relative charge on a beta-minus (β−\beta^-β−) particle.
Compare the ionizing abilities of alpha particles, beta particles, and gamma rays.
