The Quantum Theory of The Atom
The Quantum Atom
Def: Form of energy that exhibits wavelike behaviors as it travels through space. DEFINITION OF WHAT?
Heisenberg Uncertainty Principle: The more exact the position of the electron is determined, the less precisely its velocity can be known.
Pauli's Exclusion Principle: No 2 electrons can have the same 4 quantum numbers.
Aufbau Principle: The rule that electrons in the ground state will fill the lowest energy levels before the higher ones.
2) p = peanut
3) d =. double peanut
1) s = sphere
4) f = flower
LEWIS DIAGRAMS?
Hund's Rule: Every orbital must have two electrons before any one orbital could have two.
Wave-Particle Duality of Light: Principle in quantum mechanics that light is both a particle and must travel as a wave
The Electromagnetic spectrum
Visible light is a type of electromagnetic radiation.
Planck's constant and the photoelectric effect
Displacement of wave from zero. THIS PART NEEDS WORK
HOW DO YOU CALCULATE THE ENERGY OF A PHOTON?
Mathematical equation
c=入v
Characteristics of Waves
Amplitude
Wave's height from origin. to crest
Frequency
Number of waves passing a given point per second. HOW IS IT MEASURED?
Wavelength
Shortest distance between equal points on continuous waves HOW IS IT MEASURED?
Electron Configuration
The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells.
The Heisenberg uncertain principle: it is fundamentally impossible to know precisely both the velocity and position of particle at the same time
aufbau principle: from the German Aufbauprinzip, “to build” states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels
D-block elements are transition elements
More than one oxidation number (different from charge, number goes first in notation)
Orbitals: The probability of where the electron is. The electrons are too small and too fast in order to determine their exact location.
S - sphere
P - peanut
D - double peanut
F - flower
Light is one form of electromagnetic radiation, others include X-Ray and Gamma
