P4 : Nuclear Equations Flashcards
1
Q
Alpha Decay
A
An alpha particle has two protons and two neutrons
It is the same as the nucleus of a helium atom
2
Q
How are alpha particles represented
A
4
He

3
Q
Rules of Alpha Decay
A
During Alpha Decay, the atomic number decreases by 2
During Alpha Decay the mass number decreases by 4
4
Q
Beta Decay
A
In Beta Decay, a neutron changes to a proton and an electron
The electron is ejected from the nucleus, we call that a Beta particle
5
Q
How do we represent a Beta particle
A
( 0 )
( -1 e)
6
Q
Rules of Beta Decay
A
In Beta Decay the atomic number increases by 1, but the mass number does not change
7
Q
Rules of Gamma decay
A
In gamma decay, both the atomic number and the mass number are not changed at all
