1

Beta Particle

Fast electron
0
e
-1

Negative charge: -1
High velocity but low energy
No change in atomic mass, but increases atomic number by 1

2

Gamma Radiation

Electromagnetic radiation identical to light
0
y
0

No charge
Same velocity as visible light
Typically emitted together with a beta particle
No change in either atomic mass or atomic number

3

Positron Emission

0
e
+1

(Opposite of electron)

No change in atomic mass, but atomic number decreases by one

4

Alpha Particle

Helium nucleus 4
He
2
Charge: 2+
High energy, relative velocity

Atomic mass decreases by four, and atomic number decreases by two

5

Electron capture

Can be symbolized with an e- or also with a beta-.
There is no change in atomic mass but the atomic number decreases by one
