Protons, neutrons and electrons
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
Atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, as they are much heavier than electrons. The atomic mass is usually given in atomic mass units, where 1 unit is defined as 1/12 the mass of a carbon-12 atom.
The atomic mass of an atom is determined by the total number of protons and neutrons in its nucleus. Protons and neutrons contribute to the majority of an atom's mass, electrons have negligible mass in comparison. The atomic mass unit (amu) is used to express atomic mass, with 1 amu approximately equal to the mass of a proton or neutron.
By the size of the atom and its mass
Mass of an atom = mass of protons + mass of neutrons
By the atomic mass
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Essentially an atom's mass is determined by its number of protons and neutrons, as mass of electrons is so minuscule relative the nucleus.
The sum of masses of protons, neutrons and electrons.
Atomic mass.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
The atomic weight of chemical elements is determined by mass spectrometry.
