By adding the neutrons and the protons together, as the electrons are such a small part of the atom it does not matter.

Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What is the difference between relative isotopic mass and relative atomic mass?
Atomic Mass is the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.Relative atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12.Relative isotopic mass is the mass of an atom of an isotope of an element compared with one-twelfth the mass of an atom of carbon-12.Thus an element will have ONE Relative Atomic Mass but there may be MANY individual Relative Isotopic Masses for an Element (depending on how many Isotopes it has).
Atomic mass of an element?
The atomic mass of an element is the relative mass of its atom as compared with the mass of a carbon-12 atom taken as 12 units.
How is the atomic mass determined?
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
Why is the krypton atomic mass not determined?
The relative atomic mass is 83.798. So where did you get that it is not determined.

How can an atom's protons be determined?
By the atomic mass

Why is the atomic mass of an atom the average atomic mass?
It allows for the relative abundances of different isotopes.
How you determined the relative atomic mass of oxygen?
The atomic weight (not mass) of any element is determined taking into account the isotopic composition and the atomic masses of these isotopes.
What is the difference between atomic mass and relative atomic mass?
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
What is the number of atomic mass in an atom?
Relative mass number of an electron is 0
Atomic mass of an atom is determined by the combined masses of?
the atomic mass is determined by adding the weight of protons & neutrons
