Why are Neutrons necessary for a stable nucleus? Predict what would happen to the atom if there were no neutrons? (hint: think of the only element that has atoms with no neutrons)

Very interesting question indeed! I can try to explain this in following words

Explanation:

Neutrons stabilize the nucleus, because they attract each other and protons , which helps offset the electrical repulsion between protons. As a result, as the number of protons increases, an increasing ratio of neutrons to protons is needed to form a stable nucleus.

Secondly if there is no neutrons then the electromagnetic repulsion between proton will not allow any stable nucleus . Also remember in hydrogen there  is only one proton so the repulsion is not experienced hence no need of neutron.

Hope this help!!

explanation:

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
