HISTORY
Discovered the atom
What is John Dalton?
Amount of electrons in an orbital
What is 2?
Work:
1 orbital = +1/-1
Quantum
What is a unit or packet of energy
Electron Configuration
What is the arrangement of electrons in an atom?
Amount of Quantum Numbers
What is 4?
Work:
1. Principle Quantum Number
2. Angular Momentum Quantum Number
3. Magnetic Quantum Number
4. Spin Quantum Number
Particle used in Ernest Rutherford gold foil experiment?
What is Alpha particle?
Aufbau Principle states the ______ of electrons is equal to the atomic ____
What is Number?
2 types of attraction forces in molecules
What is Intramolecular & Intermolecular forces?
The range for possible quantum number values
What is 1-7
Best describes an electron using the quantum mechanical model
What is Wave?
Originated the idea that electrons demonstrate wave properties
What is Louis de Broglie
Hund’s rule suggests every orbital must be occupied by 1 _____ before any gaining another
What is Electron?
Hybridization Theory
What is atomic orbitals combine to form new hybrid orbitals
Electron configuration can be written in
What is Energy Level Diagram, Complete or Condensed Electron Configuration
information provided by the quantum numbers
What is energy level, size, shape, orientation and spin
Developed the Valence Bond Theory
What is Linus Pauling?
Pauli’s Principle implies that when an orbital is filled with 2 electrons they will spin in _____________
What is Opposite Directions?
Theory used to predict the shape of a 3-D molecule
What is VSEPR Theory/Valence Shell Electron Pair Repulsion Theory?
Group name on periodic table used to write condensed electron configuration
What is Noble Gas?
subshells that exist in n = 4 energy level
What is s, p, d, f
Work:
n = 4
l = 0, 1, 2, 3
ml = (s) 0, (p) -1, 0, 1, (d) -2, -1, 0 , 1, 2, (f) -3, -2, -1, 0, 1, 2, 3
Reason Bohr’s orbits were replaced by orbitals
What is due to the new idea of wave particle duality and the location for electrons were no longer fixed therefore, created a region of probability rather than a fixed orbit?
Heisenberg’s Uncertainty Principle concludes it is impossible to know both the exact _____ & ______ of a particle
What is Position & Speed?
Limitation of Atomic Model Theory
What is Bohr, Rutherford and Dalton could not explain why atoms of elements combine, electrons didn't lose energy and collapse into the nucleus, did not create constant energy (light) etc.
The complete electron configuration for Sulfur 1s² 2s² 2p⁶ 3s² 3p⁴, the condensed electron configuration is represented as
What is [Ne] 3s² 3p⁴
Work:
Closest Noble Gas, 1s² 2s² 2p⁶ = 10 Electrons [Ne]
Leftover configuration: 3s² 3p⁴
= [Ne] 3s² 3p⁴
Difference between Atomic and Quantum model
What is atomic model has electrons represented as a particles in fixed orbits, Quantum model electrons are treated as waves and particles and have a probable regions for the location?
