Stoichiometry

Stoichiometry. Atomic Mass. It is impossible to weigh a single atom, but one can easily establish the weight of an atom relative to another We must establish a standard: An atom of carbon-12 (six protons, six neutrons, six electrons) has a mass of exactly 12 atomic mass units (u)

Atomic Structure

Atomic Structure. Simple model of an atom. An atom is made of a tiny nucleus with electrons orbiting around it. The nucleus is made up of protons and neutrons. Much of an atom is empty space. The protons. Each proton has a +1charge. Each proton has a mass of 1 atomic mass unit.
