We have seen that isotopes differ in mass number. The mass number has very little bearing on chemical reactions; therefore thereactivityand chemical reactions of an element's different isotopes are almost identical. The physical properties of atoms, however, do depend on mass. This enables isotopes...
Because each element is distinctive of its atomic number, all atoms of a particular element must have the same number of proton. The atomic number of carbon is 6. Then all kinds of carbon atoms must have 6 protons in their nuclei. So these atoms...

Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος"place"), mea...
Stable isotope : Two or more forms of a chemical element that have a different atomic mass. The isotopic forms of a particular element differ in the number of neutrons contained in the atom's nucleus. The term stable isotope refers specifically to the isotopic forms of a chemical element ...
Complete the following chart: Isotope Practice Here are three isotopes of an element: The element is ___. The number 6 refers to the ___. The numbers 12, 13, and 14 refer to the___. How many protons and neutrons are in the first isotope? How many protons and neutrons are in the ...
There arethree isotopesof the element hydrogen: hydrogen, deuterium, and tritium. How do we distinguish between them? They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ...
The meaning of ISOTOPE is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. How to use isotope in
Most elements exist in two or more forms, known as isotopes. Isotopes have the same number of protons but differ in their number of neutrons, resulting in different masses. The lighter form is generally the more common one (Hobson & Wassenaar 2008). This variation in the relative abundance ...
