1
Q

What happens in Alpha decay?

A

The nuclei emits two protons and two neutrons

Mass and charge is conserved

2
Q

What is an example equation for Alpha Decay?

A

240 236 4
Pu -> U + He
98 92 2

3
Q

What happens in Beta Decay?

A

A neutron decays to a proton and an electron
The number of neutrons goes down by 1, the number of protons goes up by 1
Charge and Mass stays the same

4
Q

What is an example equation for Beta Decay?

A

14 14 0
C -> N + e
6 7 -1

5
Q

What happens in Gamma Decay?

A

Gamma rays don’t have mass or charge so atomic and mass number stay the same.

6
Q

What happens in Alpha Decay atomic and mass number wise?

A

Mass number goes down by 4

Atomic number goes down by 2

7
Q

What happens in Beta Decay atomic and mass number wise?

A

Mass number stays same

Atomic number goes up by 1

8
Q

What happens in neutron emission?

A

An isotope of helium, Helium-5 decays by neutron emission, charge hasn’t changed, it is the same element but the nucleus is now more stable

9
Q

What is an example equation of Neutron emission?

A

5 4 1
He -> He + n
2 2 0
