1
Q
Which number is represented by (A)
A
Nucleon Number
2
Q
Which number is represented by (Z)
A
The Proton Number
3
Q
Why don’t protons repel each other in the nucleus?
A
Due to the strong nuclear force
4
Q
Why don’t electrons collide into the nucleus?
A
Because their velocity is always changing therefore they continue in their orbit
5
Q
At what distance does the strong nuclear force work best?
A
Very short distances, but if they get too close then the force becomes repulsive
6
Q
How do you calculate the specific charge of an electron?
A
Charge / mass
7
Q
How do you calculate the specific charge of a proton?
A
Charge / mass
8
Q
How would you calculate the specific mass of an element?
A
Total number of Protons X charge / total mass of Protons + total mass of neutrons
