chemistry of the atom. atoms are most stable when their outer shell of electrons has a full quota. the first electron shell has a maximum of two electrons. the second and all other outer shells have a maximum of eight electrons. atoms tend to gain or lose electrons until their outer ...
The name indicates the mass of an atom, expressed in atomic mass units (amu). Most of the mass of an atom is concentrated in the protons and neutrons contained in the nucleus. Each proton or neutron weighs about 1 amu, and thus the atomic mass in always very close to themass (or nucl...

Atoms and elements As far as general chemistry is concerned, atoms are composed of the three fundamental particles: theproton, the neutron, and theelectron. Although the proton and the neutron are themselves composed of smaller units, their substructure has little impact on chemical transformation. ...
