The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium ( 1 H) with zero neutrons, deuterium ( 2 H) with one neutron, and tritium ( 3 H) with two neutrons.

21 lis 2024 · Many important properties of an isotope depend on its mass. The total number of neutrons and protons (symbol A), or mass number, of the nucleus gives approximately the mass measured on the so-called atomic-mass-unit (amu) scale.
19 sie 2022 · The atoms of each chemical element have a defining and same number of protons and electrons, but – crucially – not neutrons, whose numbers can vary. Atoms with the same number of protons but different numbers of neutrons are called isotopes.
28 maj 2024 · Define isotope and mass number. Determine the number of protons, neutrons, and electrons in a specific isotope of an element. Represent a single isotope of an element using the three main elemental symbolisms.
Isotopes are atoms of the same element that have the same number of protons (i.e., atomic number, "Z") but a different number of neutrons, meaning that their mass number, "A", varies. Take hydrogen, for example.
26 sie 2024 · Isotopes of any given element all contain the same number of protons, so they have the same atomic number. Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
