The total number of protons plus the total number of neutrons
Protons, neutrons and electrons
the atomic mass is determined by adding the weight of protons & neutrons
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
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.
The atomic number of an atom is determined by the number of protons it has.
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
the atomic mass is determined by adding the weight of protons & neutrons
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.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
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.
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.)
Carbon (12).
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
