Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
The total number of protons plus the total number of neutrons
No, only by the atomic number, also known as the number of protons.
it is the sum of the protons and neutrons present in the nucleus of the atom.
the number of protons in an atom and the number of electrons in an atom
Mass of an atom = mass of protons + mass of neutrons
Protons, neutrons and electrons
the mass number is determined on the number of protons and neutrons in the nucleus of the atom.
7, Atomic number is determined by the number of protons in a atom
the atomic mass is determined by adding the weight of protons & neutrons
