Question: Isotopes are atoms of the same element with the same number of protons and a different number of: A. ions B. molecules C. electrons D. neutrons Atoms: Atoms are classified into various types based on differentiated featu...
Isotopes同位素 Although an element contains only atoms with the same atomic number, these atoms, however, may have different mass numbers. For example, there are three different kinds of carbon atoms. One has a mass number of 12 and the other two re...

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
An isotope is an atom with the same number of protons but a different number of neutrons. Thus, they have different atomic weights. This is important to know because there is a such thing as a radioactive isotope. These elements just have additional energy, and they release radiation in ...
n.Atoms of an element having different numbers of neutrons in their nuclei, and hence, different mass numbers. Isotopes of a given element have the same number of nuclear protons but differing numbers of neutrons. Naturally occurring chemical elements are usually mixtures of isotopes so that observ...
