Isotopes are variations of elements with the same number of protons but different numbers of neutrons, affecting mass. Isomers have identical molecular formulas but differ in atom arrangements or bonds, influencing structure and properties. Difference Between Isotopes and Isomers ...
Allotropes are different forms of the same element with distinct physical or chemical properties; Isotopes are atoms of the same element with differing numbers of neutrons.

Chemical elements can exist as two or more isotopes that have different numbers of neutrons in the nucleus. For example, while carbon always has six nuclear protons, it exists as three different naturally occurring isotopes with six, seven or eight neutrons. These isotopes are often written carbon...
“isotope” of the element. Isotopes are formally defined as elements with the same number of protons, but a different number of neutrons in the nucleus. Another definition of isotopes defines them as atoms with the same atomic number (number of protons), but different atomic mass numbers (...
are. For most elements, a change of one or of a few mass units is such a small percentage of the total mass that the chemical differences betweenisotopesare negligible. For hydrogen, however, chemical reactions involving the different isotopes proceed at measurably different rates. These kinetic-...
Isotopes - isotope: atoms of the same element that have different numbers of neutrons - Carbon, as found in nature, is a mixture of isotopes, including atoms of carbon-12, carbon-13, and small amounts of carbon-14. Isotopes atomic weight - The atomic weight of an element is the weighted...
<p>To solve the question regarding isotopes, we need to understand the definitions of mass number and atomic number, as well as the characteristics of isotopes.</p><p>1. <strong>Understanding Isotopes</strong>: - Isotopes are variants of a particular
F. W. Aston, who took as his subject "Elements and Isotopes". That a chemical element could consist of isotopes of different atomic mass was first observed by Soddy when working on the products of radioactivity. Proof that this was true of the elements generally could only be obtained by ...
