Many stable atoms have ‘magic numbers’ of protons and neutrons − 75 years ago, 2 physicists discovered their special propertiesTin always has 50 protons, and its most common isotope has 70 neutrons. Isotopes are atoms of the same element that have a different number of neutrons. There are nine other stable isotopes of tin ...
