Propose a reason why a nucleus with 6 protons and no neutrons is unstable.Hint: Remember that all protons are positively charged.

A nucleus with 6 protons and no neutrons would be unstable due to the repulsive forces between the protons. Here's a step-by-step explanation:

1. Protons, which are found in the nucleus of an atom, carry a positive charge.

2. According to the laws of physics, like charges repel each other. This means that the protons in the nucleus will try to push each other away because they all carry the same type of charge.

3. In a stable nucleus, this repulsion is balanced by the strong nuclear force, which is a powerful attractive force that acts between protons and neutrons.

4. If there are no neutrons in the nucleus, like in this case, there is nothing to balance out the repulsive force between the protons.

5. As a result, the protons will push each other away, causing the nucleus to become unstable and break apart.

So, the reason why a nucleus with 6 protons and no neutrons is unstable is because there are no neutrons to help balance out the repulsive forces between the protons.
