Expert Answer
how protium is so much stable?
we know that in protium there are no neutrons. But if there are no neutrons then how is it stable???
1H is the most common hydrogen isotope with an abundance of more than 99.98%. Because the nucleus of this isotope consists of only a single proton, it is given the descriptive but rarely used formal name protium. It is stable in gaseous form as H2. Protium or H as such is not stable.
Neutrons are necessary within an atomic nucleus as they bind with protons via the nuclear force; protons are unable to bind with each other (see diproton) due to their mutual electromagnetic repulsion being stronger than the attraction of the nuclear force.
Since, there is no other proton in hydrogen, it doesnt need neutron.
The answer of other part --- and if it is stable without neutrons then why other elements require neutrons?? they even can be without these neutrons... lies there only.
