What is the uncertainty principle?
The principle states that we are unable to determine an electron's exact momentum and position
What is the de Broglie's eqauation?
wavelength = h/mv
In de Broglie's equation, what is velocity proportional to?
velocity is proportional to wavelength
In the de broglie's equation, what is position related to?
Position is related to particle matter
What does the principal quantum number represent
The "n" value represents the location, size and energy level of the orbital
How can you find an electron's energy level?
En= -2.18x10^-18((1/n^2f)-(1/n^2i))
What could the possible "n" values be?
n could equal to any number from 0-9
What does the angular momentum quantum number represent?
it represents the shape of the orbital
how can you determine the "l" value?
