Front 6

E = ????

Back 6

hƒ = hc/λ

Front 7

electromagnetic spectrum low NRG to high

Back 7

radio → μ → IR → ROYGBV → UV → X → γ

Front 8

Plancks constant

Back 8

h = 6.6 x 10⁻³⁴

Front 9

Energy of an energy level equation

Back 9

E = -R / n²

Front 10

Quantum numbers

Back 10

n = NRG level 1-7
l = sub orbital s-f which is 0-3
m = magnetic number = same NRG = # of orbital orientations
....-1,0,1

spin - up or down = +1/2 or -1/2

Front 11

Afbau exception

Back 11

e⁻ will fill across the periodic table as it is arranged, but when you start taking electrons off you have to remove electrons with highest principle quantum number first. Which means 3d orbitals fill before 4p, but do not remove electrons until after 4s

Front 12

diamagnetic

Back 12

all electrons paired. weakly repelled by magnet

Front 13

paramagnetic

Back 13

at least one unpaired electron. weakly attracted to a magnet.

Front 14

radical

Back 14

unpaired electron.

Front 15

thermochemistry of nuclear reactions

Back 15

All exothermic

Front 16

mass defect

Back 16

∆E = ∆mc²
mass lost in the progress of the reaction
∆E = binding energy parent - binding energy daughter
