Chemistry Atomic Number = # of protons Mass Number = # of protons + # of neutrons Ionic = metal and nonmetal (transferred) Covalent = nonmetal and nonmetal (shared) Metallic = metal and metal (pooled) Photons o Alpha – positive charged, most massive Mass number decreased by 4, atomic number decreased by 2 o Beta – negative charge o Gamma Isotope - Atoms with the same number of protons, but differing in the number of neutrons present in the nucleus. Most elements have more than one isotope. Photon - The smallest unit of light. The photon is often described as a electromagnetic wave or wave packet. Light photons from red to blue in the visible spectrum have increasing energy. X-rays and gamma rays are energetic photons with thousands to millions of times the energy of light photons. diamagnetic - all electrons paired paramagnetic - unpaired electrons Principle Quantum Number (n) o Integer that determines overall size and energy of orbitals.
