- 1Niels Bohr ExperimentLine Emission Spectra
- 2Neils Bohr conclusion of experimentElectrons are found only in specific circular paths called orbitals around the nucleus.
Electrons are in a fixed energy = Energy Levels
Energy levels are also called “principal quantum numbers”
Energy levels correspond to the rows of periodic table - 3Neils Bohr Model of AtomSolar system model
Electrons gain or lose energy by changing orbits
Colors depend on the number of energy levels jumped
- 4The energy level normally occupied by an electronGround state
- 5When energy gets added to an atom, the electrons "jump" energy levels to ...An Exited State
- 6When the electrons lose that energy and return to it's ground state, the energy lost is emitted as...Light
- 7WavelengthThe length of one wave between identical points.
- 8FrequincyThe number of waves that pass a point in a given amount of time.
- 9What is plank's constant?6.6262 x 10-34
- 10What equation do you use when you are finding ENERGYE = h x v
- 11What equation do you use when you are finding MASS
- 12Erwin Schrodinger Experiment/EvidenceUsed emission line spectrum and advanced math to describe the behavior of electrons.
- 13Erwin Schrodinger Conclusion of ExperimentThe S,P,D,F sublevels
- 14How many electrons can the s sublevel hold?2 electrons
- 15How many electrons can the p sublevel hold?6 electrons
- 16How many electrons can the d sublevel hold?10 electrons
- 17How many electrons can the f sublevel hold?14 electrons
- 18Werner Heisenberg ExperimentNone, just lots of math
- 19Werner Heisenberg conclusionHe created the "Heisenberg Uncertainty Principle" which states that the more precisely the position of an electron is known, the less precisely its momentum can be known
- 20Werner Heisenberg Model of Atom (Latest one)Quantum Mechanical Model - Electron Cloud
- 21What is the rule 1of energy level diagrams? (Aufbau Principle)An electron occupies the lowest energy level that it can before moving up to a higher energy level
- 22What is the rule 2 of energy level diagrams? (Pauli Exclusion Principle)When occupying sublevels within an energy level, electrons must have opposite spins
- 23What is the rule 3 of energy level diagrams? (Hand's / urinal rule)There must be an electron in each orbital before they will pair up.
- 24—Energy level (the row)
- 25—Type of Orbital (s,p,d,f)
- 26—The number of electrons in this orbital (number of spots in this orbital)
- 27Valence ElectronElectron in the outermost energy level. Furthest from nucleus.
- 28Where do we see valence electrons in electron configurations?Only those electrons in the "s" and "p" subshells in the highest energy level.
- 29What is the maximum amount of Valence Electrons?maximum = 8
- 30How do you draw valence electronsElectron dot diagrams (one on each side before any pairs are made)
