Key fact. Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and...
Sep 26, 2024 · An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

Jun 26, 2023 · Understand how isotopes differ in particles and mass. Identify the most abundant isotope when given specific values. Calculate the atomic mass of an element from the masses and relative percentages of the isotopes of the element. Define LEU/HEU with percentages and applications.
Isotopes are atoms that have the same number of protons but different numbers of neutrons. Thus, atoms of #""_6^12"C"# and of #""_6^13"C"# are isotopes of each other. They both contain 6 protons, but one contains 6 neutrons and the other contains 7 neutrons.
Atoms of the same element (i.e., same atomic number, Z) that have different numbers of neutrons are called isotopes. For example, 99% of the carbon atoms on Earth have 6 neutrons and 6 protons in their nuclei; about 1% of the carbon atoms have 7 neutrons in their nuclei.
Sep 13, 2019 · All isotopes of an element have the same atomic number and number of protons, but they have different atomic masses from each other. Isotopes of an element share similar chemical properties, but have different nuclear properties. Every element has isotopes. The 81 stable elements have 275 isotopes.
