While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element ...

All three isotopes of hydrogen have identical chemical properties ... An isotope is named after the element and the mass number of its atoms. For example, carbon-12 is an isotope of carbon ...

There are three isotopes of hydrogen: hydrogen ... They have the same mass number but if the number of protons is different, they are different elements.

ALTHOUGH the separation of the two hydrogen isotopes which occurs on electrolysis must be closely connected with their over-potentials, no measurement of these has been published. A comparison of ...

Most elements exist in two or more forms, known as isotopes. Isotopes have the same number of protons but differ ... of stable isotopes results from tiny mass differences that cause the isotopes ...

For this purpose, they must be separated using highly sophisticated techniques, such as mass spectrometry. While deuterium H-2, an isotope twice as heavy as hydrogen, is predominantly used in ...
