SOL Review #2: Electrons in atoms
Terms in this set (11)
Horizontal distance between the crests or between the troughs of two adjacent waves
The number of complete waves that pass a point in a given time
Planck's constant = 6.626x10^-34
Particles of light
-Electrons are in energy levels, the further an electron was from the nucleus, the higher its energy
-developed the planetary model
-Electrons travel in distinct orbits and there are only certain allowed orbits, but electrons can move to different orbits.
-Electrons absorb and emit energy in discrete amounts (quanta) as they move from one orbit to another.
-Hydrogen's atomic emission spectrum results from electrons dropping from higher-energy atomic orbits to lower-energy atomic orbits.
Louis de Broglie
-electrons have both wave and particle characteristics
-electrons are restricted to certain energy levels and to certain wavelengths and frequencies
-the deBroglie equation predicts that all moving particles, no matter the size, have wave characteristics
-The Uncertainty Principle: position and speed of an electron cannot be determined at the same time
-derived mathematical equations that treat hydrogen's electron as a wave
-the solution of the equation gives a probability of finding an electron
-3d atomic orbitals (s,p,d,f) describe the electron's location
Electrons will occupy the lowest energy level available
Pauli Exclusion Principle
Max of two electrons per orbital, both opposite spins
