Radioactivity (A-level only)

Which row in the table is correct for alpha ( $α\alpha$ ), beta-minus ( $β−\beta^-$ ), and gamma ( $γ\gamma$ ) radiation?

Deflected by a magnetic field? (alpha: yes, beta-minus: yes, gamma: yes)

Typical range in air (alpha: a few cm, beta-minus: a few m, gamma: virtually infinite)

Electric charge (in units of $e$ ) (alpha: $+ 1$ , beta-minus: $- 1$ , gamma: $0$ )

Relative ionizing ability (alpha: lowest, beta-minus: medium, gamma: highest)
