Hey there!
Your answer is no.
The difference between isotopes is the number of neutrons, not the number of protons.
For example, we have carbon-12 and carbon-14, two different isotopes of carbon. One has 6 protons and 6 neutrons, while one has 6 protons and 8 neutrons. They have the same amount of protons.
If you change the number of protons, then you have a different element. Isotopes are the same element.
Hope this helps!
