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.1. Understanding Isotopes: - Isotopes are variants of a particular
Isotopes of an element have substantially the same chemical and. physical properties and it is 13 a difficult matter to separate them. So far as there are methods of isotope separation they depend upon quite small differences; upon differences in properties more or less directly associated with th...

mainly refers to the variation in the atomic mass or weight of an element. it is also defined as variants of a particular element where these variants will have the same number of protons but differ in the number of neutrons in the atom. due to the unequal numbers of neutrons, the ...
The versions of anelement with different neutrons have different massesand are called isotopes. The average atomic mass for an element is calculated by summing the masses of the element's isotopes, each multiplied by its natural abundance on Earth. ...
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...
