The number of neutrons is represented by the neutron number ( N ). Because the mass of these nuclear particles is each approximately equal to one unified atomic mass unit (u), the sum of the protons plus neutrons is designated as the mass number ( A ). The mass of the electron is ...

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. Right, it's one proton in the nucleus. And that's imp...

Atomic mass is the average weighted mass number of all isotopes of a given element. It is calculated based on the frequency of different isotopes of that element. Atomic number is the number of protons in an atom's nucleus. It is the same for all atoms of a given element. What is the...

as an integer value. Different isotopes have different mass numbers, because their numbers of neutrons vary. Therefore, the mass number of an element gives the mass of the element in integers. The difference between the mass number and the atomic number of an element gives the number of neutro...
The total number of protons and neutrons in the nucleus is called the mass number. ? Number of neutrons = atomic mass – atomic number Isotopes (copy this slide) ? Isotopes are atoms of an element that differ by the number of neutrons in the nucleus. ? Isotopes of an element are ...
