Protons, neutrons and electrons
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
the atomic mass is determined by adding the weight of protons & neutrons
Protons, neutrons and electrons
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
By the size of the atom and its mass
Mass of an atom = mass of protons + mass of neutrons
By the atomic mass
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
Essentially an atom's mass is determined by its number of protons and neutrons, as mass of electrons is so minuscule relative the nucleus.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
Atomic mass.
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
the atomic mass is determined by adding the weight of protons & neutrons
The atomic weight of chemical elements is determined by mass spectrometry.
