Chem Ch 4 Dmitri Mendeleev Found 65 elements as well as their relative masses and chemical properties. The Rhymburg Equation 1 1 1 =R( 2− 2) λ nf ¿ Coulomb’s Law q1q2 r ) E=9E9¿ Orbital energy increases by n, meaning 2s has more energy than 1s, and increases across the blocks from s to p to d Orbital Rules and Principals  Pauli Exclusion Principal states that no two electrons can have exactly the same quantum numbers  Aufbau Principal states that electrons fill from the lowest shell available first before filling any other shell ie 1s fills before 2s
