The nucleus of each atom contains protons and neutrons. 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, ...

Learn what mass number and atomic number tell us about the protons, ... There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium (hydrogen-3): ...

AFTER the discovery by Urey of the isotope of hydrogen of mass 2 (deuterium) and its concentration by electrolysis, it was natural to examine whether any other stable isotopes of hydrogen, and ...

Atomic Number (Z)=Number of Protons. Example: Hydrogen: The simplest atom, hydrogen, has 1 proton in its nucleus. ... So, the mass number of this chlorine isotope is 35. Example 2: Potassium.

Atoms with the same number of protons but different numbers of neutrons are called isotopes. They share almost the same chemical properties, but differ in mass and therefore in physical properties.

Gas source, gas chromatography isotope ratio MS. The second Thermo 253+ isotope ratio mass spectrometer in the CUBES SIL is configured for continuous flow mode and equipped with a gas chromatography ...

The article, “Isotope-dependent site occupation of hydrogen in epitaxial titanium hydride nanofilms,” was published in Nature Communications at DOI: 10.1038/s41467-024-53838-6 .

All the deuterium atoms—an isotope of hydrogen with double its mass—were at locations in the titanium crystal known as tetrahedral positions. However, 11% of the hydrogen atoms present were at ...
