It is convenient to describe the composition of an atom in terms of the number of protons and neutrons in its nucleus (Figure 1 ). The term atomic number , conventionally denoted by the symbol Z , indicates number of protons present in the nucleus of an atom, which is also equal to ...
As target nuclei, we take $^{6}$He and neutron-rich Ne isotopes in addition to stable nuclei of mass number $A=4$--$208$ in order to clarify mass-number and isotope dependence of $U$. The local potentials reproduce the experimental data systematically and have geometries similar to the...
So deuterium has one neutron and since neutrons have mass, deuterium has more mass than protium. So isotopes have different masses because they differ in terms of number of neutrons. Notice though, that they have the same atomic number, they have the same number of protons in the nucleus...

Isotopes are the atoms of same element, they have same atomic number but different mass numbers. Isotopes have different number of neutrons in their nucleus . If an element exists in two isotopes having atomic masses 'a' and 'b' in the ratio m:n, then average atomic mass will bem×a+n...

Isotopes are atoms of the same element that have a different number of neutrons. Neutrons are subatomic particles that make up the nucleus with protons. Protons never change between atoms of the same element and are the defining feature that makes an atom part of an element....
Two or more atoms having the same atomic number but the different mass numbers can be known as isotopes. The atomic number denotes the number of protons inside the nucleus of an atom. The number of protons remains the same for all isotopes....
