Chemistry Photon or a living Room Photon? Let's get on the same wavelength.

neutral, N/A

Photon units

Frequency: Hz or s^-1

Wavelength: nm or m (m is always used in equations)

wavelenngth and Frequency

when frequency increases, wavelentgh decreases

Light spectra

electrons go to excited state than backto groudn state, emit energy and photons

Quantum numbers

Angular Momentum (shape of orbital, based on shell)

Magnetic (use number line, orientation of orbital)

Spin (+ or - 0.5, electron spin)

Electron configuration

1 s2, etc

Pauli’s Exclusion principle

no electrons are the same, excluded

Hund’s Rule

every orbital is slighty occupied

Aufbau principle

electrosn fill orbital starting from nucleus out

Photoelectric effect

KE electron = E photon - photoelectric energy

Effective Nuclear Charge Zeff

Zeff = proton # - core electrons

The Shielding Effect

inner electron repel electron from outer shells

Columbus Law

attraction/ repulsion is tronger when

particles charge is greater

distance is shorter

Isoelectric Series

atoms/ ions with same electron configuration

Photoelectron Pectroscopy

A process which measures the binding energy that the nucleus has for its electrons

attraction between charged particles increases as the distance between them decreases
