True

Explanation:

Here is the complete question

Positively-charged particles consisting of two protons and two neutrons emitted by radioactive materials are alpha particles. True or False

Answer

Positively-charged particles consisting of two protons and two neutrons emitted by radioactive materials are alpha particles.

This is because alpha particles consist of two protons and two neutrons. They are helium atoms that lost two electrons.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
