Which, if any, of the following statements are true?

1)The nuclear force acts between a proton and an electron.
2)All radioactive nuclei decay.
3)Nuclear forces are negligible at distances larger than a few fm.
4)The nuclear force acts between a proton and a neutron.
5)The resistance of a semi-conductor increases exponentially as the temperature of the semi-conductor is reduced.
6)A semi-conducting diode is formed by either an n-p-n sandwich or a p-n-p sandwich, where n and p refer to the types of semiconductors.
