Follow these simple steps to find the number of protons, neutrons, and electrons for an atom of any element.
Atomic Structure Protons, Neutrons, and Electrons Section 4.3 Distinguishing Among Atoms Just as apples come in different varieties, a chemical element can come in different “varieties” called isotopes. 4.3 Protons Protons- determine the identity of an atom –Elements are different because they each...

Electrons form a spinning cloud around the nucleus. Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All...
