• the number of protons in the nucleus

• the size of the nucleus

What does this symbol tell you?

• the radioactivity level

• information about the nucleus

As the distance between particles increases, what happens to the strength of the nuclear force?

• decreases

• increases

• remains unchanged

The large attractive force that holds the nucleus together

• strong nuclear force
