E⁰ cell

cathode - anode

ΔG⁰

-nFE°

Ecell

0.02567/n × lnK

ΔG⁰ for the same element different electrons

ΔG°(1) - ΔG°(2)

Nearst equation

Ecell- (0.0592/n) log Q

current

charge/time

Alpha particle

4 He
2

Beta particle

0 e
-1

Gamma (γ) Emission

0 γ
0

positron

0 e
⁺1

electron

0 e
-1

decay rate

λN

half life (t½)

0.693
t½ = -----
λ

- λt (integrated rate law)

ln (nt/n₀)
N₀= amount of isotope at 0
Nt= amount of isotope at t

radioactive decay law

Nt= N0e-λ

radioactive decay law solving for time

t = -ln{At/A0}/λ

mass defect

mass of proton +mass of neutrons − mass of isotope

reduction

electrons on the reactant side

oxidation

electron on the product side

K

− GΔ °/RT
e
