The Atomic Mass or mass of an atom is locaed at the bottom of a sqaure on the Periodic Table. The atomic mass= atomic number (protons/neutrons)+electrons. Enable to find the number of electrons you must
They are measured in atomic mass units (amu)
the kilogram Is the SI unit

These particles are protons and neutrons; but to be correct the mass of electrons must be added.
Protons plus the neutrons
Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a calcium atom = Mass number - 20
The earth is magnetic because of the mass of molten iron in its core. Magnetism come from subatomic attraction of particles in some elements including iron and carbon.
Sulfur has 16 protons and electrons; the number of neutrons is specific for each isotope: Number of neutrons in a sulfur isotope = Mass number - 16

The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
