the atomic mass is determined by adding the weight of protons & neutrons
The atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. While electrons contribute very little to the atomic mass, the protons and neutrons, found in the nucleus, account for the majority of an atom's mass.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
The relative atomic mass of an atom can be determined by averaging the masses of its isotopes based on their abundance in nature. This value is reported relative to the mass of a carbon-12 atom, which has been assigned a relative atomic mass of exactly 12.ø
The atomic number of an atom is determined by the number of protons it has.
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 masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.

The atomic number of an atom is determined by the number of protons it has.
The atomic mass is the can be determined by the number of protons in an atom. Remember that a proton has an atomic mas number of 1 AMU (atomic mass unit). (The total mass of an atom is the protons, neutrons and electrons combined.)
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
Carbon (12).
The sum of masses of protons, neutrons and electrons.
The mass of 1 mole of an element is determined by summing the atomic masses of each atom in the element's chemical formula. This value is typically expressed in grams per mole, referred to as the molar mass. It is based on the relative atomic masses of the isotopes that make up the element.
By the atomic mass
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
