The mass number is the average Atomic Mass of all the isotopes that are found in nature.
The mass number is the sum of neutrons and protons.

Protons and Neutrons
The element's average atomic mass.
Platinum is a metal element. Atomic mass of it is 195.08.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
If you think to the number of protons in an element atom this number is equal to atomic number of this element. The calculation of the mass of the proton and other properties are another questions and problems.
the total number of protons and neutrons in the nucleus.
The Atomic Mass is equal to the number of protons and electrons that an element has.
The number of protons, electrons, and neutrons:P
The sum of the number of protons and the number of nuetrons.
The atomic mass of an element is equal to the number of protons.
The element's average atomic mass.
Platinum is a metal element. Atomic mass of it is 195.08.
The atomic mass in an element is the total number of protons and neutrons in an atom's nucleus.
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The atomic mass number does not equal the number of electrons in the element. The atomic number, on the other hand, does usually equal the number of electrons in the element, With the exception of ions.
The mass number of an element is equal to the number of protons plus the number of neutrons.
