Mendeleev Based "Periodic Table" on Atomic WEIGHT
Moseley Based "Period Table" on Atomic NUMBER
Atom The basic particle from which all elements are made
Atomic Number The number of protons in the nucleus of an atom
Proton a positively charged particle that is part of an atom's nucleus
electron a negatively charged particle that is found outside the nucleus of an atom
neutron a small particle in the nucleus of the atom with no electrical charge
Isotope an atom with the same number of protons and a different number of neutrons from other atoms of the same element
cloud model of atom according to the cloud model, electrons move rapidly in every direction around the nucleus
Bohr's model of an atom Bohr suggested that electrons move in specific orbits around the nucleus of an atom
atomic weight atomic mass
