Wavelength x frequency
Short wavelength, high frequency, high energy—>Long wavelength, low frequency and energy
Gama X-rays UV Light:VIBGYOR IR Microwaves Radio(FM-->AM) Long Radio
Pauli Exclusion Principle
Orbital can only have 2 electrons

He has how many valence electrons?

Protons effect on atom size
More protons shrink the atom
Size trend
Down and left
Ionization energy trend
Up and right
High IE harder to lose electron
Metallic character trend
Down and left
Electron affinity trend
Up and to the right
Excludes noble gases and middle section
Ionization energy
Energy to remove an electron
Smaller atom harder to remove
Removal of an electron is a … Process
Endothermic
E moves from low to high energy level
Absorbs energy
E moves from high to low energy level
Releases energy–> light–> emission spectra
Metallic character
Loses e- easily, conductivity is high, it’s malleable
Electron affinity
Wants to gain an e-
Ionic radius
Cation
How to compare the sizes of isoelectronic species
Most protons=smallest
n
Principle quantum #
L
Subsidary quantum number
