These are both true or false:
As a nucleus gets larger,neutrons tend to change into protons and electrons?
To have the potential to be radioactive,a nucleus must always be very large?

The first is false and the second is true.

A large nucleus is not required for an atom to be radioactive. Deuterium and Tritium, hydrogen with one and two neutrons, respectively, are both radioactive due to their instability, tritium being the more unstable of the two. I hope that you realize that hydrogen has only one proton.
For the first question about an enlarging nucleus, the answer is yes. If an atom has become unstable by absorbing too many neutrons, it will undergo what is called Beta minus decay. This is when a neutron ejects an electron out of the atom and converts itself into a proton.
Hope this helps

the first one is FALSE * i don't think so*
the second one is TRUE*coz those elements are radioactive which have atomic no. more than 82*
