|
|
What is Beta radiation? |
A beta particle is a fast moving electron, it has no mass and a charge of -1 |
|
|
When happens when Alpha is emmited? |
The elements mass decreases by 4 (loss of 2 protons+2neutrons) and atomic number decreases by 2 (loss of 2 protons) A new element is formed due to the loss of protons |
|

What happens when beta radiation is emitted? |
