Question

A free neutron decays into a proton but a free proton does not decay into neutron. This is because (A) neutron is an uncharged particle (B) neutron has larger rest mass than proton (C) neutron is a composite particle made of a proton and an electron (D) proton is a charged particle

Tardigrade Admin · Accepted Answer

As neutron has more rest mass than proton it will require energy to decay proton into neutron. Option 4
