Equations Flashcards
1
Q
The energy of an electron in an atom
A
-1/n^2 * 13.6 eV or -2.178E-18 Joules / n^2 where n = the shell number. (I believe this only works for single shelled elements).
2
Q
eV
A
An electron volt. A unit of energy equal to about 1.6×10−19 joules.
3
Q
Jourles.
A
A unit of energy.
4
Q
Quantization of energy of photons equation.
A
Ephoton = nhv where n is a positive integer, h is planck’s constant, and v is the frequency of the light.
5
Q
Quanta
A
The discrete amounts of energy photons carry.
6
Q
Energy of a photon (as a wave)
A
E = hv
7
Q
Energy of a photon (as a particle)
A
E = mc^2
8
Q
Number of electrons in outer shell
A
2n^2
