Frage 109

Which description correctly defines isotopes of a single element?

Same proton count but different neutron countsRichtige Antwort
Different proton counts but the same element name
Same neutrons but necessarily different elements
Different electron counts only, regardless of nuclei

Erklärung

Isotopes retain the same proton count, which preserves element identity, but contain different numbers of neutrons. Changing the proton count would create a different element rather than another isotope of the original one.
