Question

Could a nucleus that has more than one proton but no neutrons exist?Explain.

Answer 1

Answer:

No, it does not exist.

Explanation:

Hello,

Taking a look into the atom, one must remember that the number of neutrons is computed via:

$\#Neu=Atomic.mass-Atomic.number$

In such a way, if a nucleus has no neutrons and more than 1 protons (equal to the atomic number) the only possibility is that its atomic mass equals the atomic number (it is just the case of hydrogen) nonetheless, without any neutrons, the protons will repel each other since the nucleus would have multiple positive charges, thus, it does not exist.

Best regards.

Answer 2

A nucleus can't have more than one proton but no neutron in a nucleus.

This is as a result of the protons and neutrons acting hand in hand to stabilize the nucleus. Let's assume we have two protons in a nucleus, the force of repulsion will become greater than the binding force which will drag them apart and cause it not to exist.

The presence of the protons but no neutrons will bring some negative effects on reactivity. The nucleus won't be able to reactive with others to form new compounds.
