Element story
From protons to elements
Start with the nucleus
Carbon-12 has 6 protons and 6 neutrons; changing the proton count would create a different element.
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. Their chemistry is very similar, while their masses and nuclear stability can differ.
