Question

Match the atomic particles with their characteristics.

1. atomic mass = 4
2. mass of electron; positive charge
3. 100 percent energy; zero mass
4. mass <1; unstable charge (+)
5. electron emitted from the nucleus

alpha
gamma
meson
beta
positron

Answer 1

alpha: atomic mass = 4

beta: mass of electron; positive charge

gamma: 100 percent energy; zero mass

positron: mass <1; unstable charge (+)

beta: electron emitted from the nucleus

Note: Mesons are particles composed of a quark and an antiquark and do not fit the descriptions provided.
