Web2.6 Stable Isotopes Stable isotopes are atoms of the same chemical element (i.e. the same number of protons and electrons) with a different number of neutrons that do not undergo radioactive decay, but they may be present as a result of radioactive decay. Ratios of different stable isotopes of the same element can provide useful indicators of water … WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the …
