Question 197: Atoms & Nuclei

Question

The decay of a proton to neutron is :

Accepted Answer

Positron emission or Beta plus decay is a subtype of radioactive decay called Beta decay, in which a proton inside a nucleus is converted into a neutron while releasing a positron and an electron neutrino.
So, decay of a proton to neutron is possible only inside the nucleus. Free proton cannot decay to neutron as mass of proton is less compared to neutron so to decay into higher mass, proton need extra energy which free proton canÃ¢ÂÂt get, only proton inside nucleus can get.

Answer

always possible as it is associated only with $$\beta$$
+
decay

Answer

possible only inside the nucleus

Answer

not possible as proton mass is less than the neutron mass

Answer

not possible but neutron to proton conversation is possible
