Question

Gamma, beta and alpha radiation are all alike because:


they all have the same mass

they all have the same charge

they all can be emitted from the nucleus of an atom <---

they all have the same energy




Alpha particle emission occurs when:


the nucleus has more than 83 protons <---

the ratio of neutrons to protons in the nucleus is too high to be stable

the nucleus has a mass of more than 82 amu

the ratio of neutrons to protons in the nucleus is not exactly balanced

Answer 1

Gamma is a EM radiation, so there's no mass

Answer 2

so my answers are correct?

Answer 3

yes
