One member of a family of chemical elements that has the same chemical properties (the same atomic number) but differs in mass. Isotopes have the same number of protons and electrons, but a different number of neutrons. The mass is determined by the total number of nucleons (neutrons and protons). See allotrope.

- A new career: isotope designerScale CorrectionPlease note, you have misinterpreted Sherrill's quote regarding the scale at which he works. He said he works *at* the scale of the atomic nucleus, 100,000 times smaller than the *nanoscale* - not 100,000 times smaller than the atomic nucleus.Thanks,Brian Hawthorne
