Vocabulary and Definitions
Atom - The smallest object that retains properties of an element. Composed of electrons and a nucleus (containing protons and neutrons). Atomic Number - Number of protons in an element.
Orbitols - An energy state in the atomic model which describes where an electron will likely be.
Nucleus -The central part of an atom that contains the protons and neutrons. Plural nuclei.
Photon - Massless packet of energy, which behaves like both a wave and a particle.
Proton - Particle found in a nucleus with a positive charge. Number of these gives atomic number.
Valance Electrons - The electrons in the outermost shell of an atom.
Single Bond - When an electron pair is shared by two atoms.
Quantum Numbers - Set of numbers used to completely describe an electron.
