Major Points• Types of Radiation (Radio waves, microwaves, infrared, etc.)
• Speed Equation (Speed = wavelength x frequency) • Energy Levels (What happens when an electron becomes energized?) • Pauli Exclusion Principal • Orbital Shapes (S, P, D) • Electron Configuration (Writing out the configuration of the electrons of an element using s, p, and/or d) • Orbital Diagramming (How to diagram the orbitals of an element's electrons using boxes and arrows) • Ionization Energy and Electronegativity in Relation to the Size of an Atom (List the elements from largest to smallest according to their electronegativity, etc.) |
