Our question says it wants us to write three basic equations that would allow us to derive the expressions for the allowed radii and the allowed energy of electron states in the bore model of the hydrogen atom, or at least the bore model of the atom, which only works for hydrogen.

So boar's postulate states that the electron can revolve around the nucleus only in those orbits for which its angular momentum l is equal to the integral multiplied by planx constant over 2 pi.
00:29
Or in other words, l is equal to n times plank's constant h over 2 pi.
00:43
Where here, n is some kind of principal quantum number.
00:46
It's an integer value and it's equal to 1, 2, 3, 4, so on.
00:50
So that's actually one of the equations.
00:52
So you can box that in.

Another one, the force acting on an electron due to the nucleus can be determined by using kulom's law.
01:02
So it says that force on an electron is directly proportional to the product of magnitude of charge and inversely proportional to the square of distance between the nucleus and the electron.
01:13
So the coolum force, f, is equal to k subc times z e squared over r sub n squared, where k sub c is the proportionality constant, e is the charge of an electron, and z is the aty squared.
