1
Q
What distance is the strong nuclear force repulsive froom
A
0.5 fm or closer it is repulsive
2
Q
What distance is the strong nuclear force attractive from
A
0.5fm - 3fm highly attractive
3
Q
What does the attraction and repulsion of the strong nuclear force ensure
A
nucleus stays together but doesn’t collapse

Q
What is alpha decay
A
nucleon number reduced by 4
proton number reduced by 2
Helium (alpha particle emitted)
5
