quantum numbers updated

schrödinger wave equation

describes quantized energies of the electron and shows probability of finding electrons

solving wave equation

gives set of orbitals and their energies

quantum numbers

locate position of electron

four quantum numbers

primary, angular momentum (secondary), magnetic, spin

principal quantum num

n; size and energy of atomic orbitals and represents energy levels the electrons can occupy

max number of electrons per energy level

2n²

angular momentum

sub levels contained within n, each sub level has diff shape

l formula

n-1

magnetic quantum number

represents orientation, -l to l

spin quantum number

represents spin of electron,

energy level diagrams

represents energy level, sub shell, and orbital thay r occupied by electrons

pauli exclusion principle

• no two electrons in an atom can have the same four quantum’s numbers

• only electrons of opposite spin can occupy an orbital

aufbau principle

• place electrons in the orbitals in order of increasing energy level

hunds rule

• wheb electrons r added to orbitals of same energy sub levels, each orbital receives an electron before pairing begins

electron configuration

shortway of showing number and arrangement of electrons in an orbital
