For that problem we have according to a bullet model the radiance of the ion atom is quantized as follows here are n is just equal to 0 .05 to 9 nanometers times n squared or 0 .0529 times n 9 n squared and here n is just an integer a positive integer so now so for n is just equal to 1, we have u, which is the electrostatic potential, energy, which is equal to.
00:48
For this is now the energy, this is just the electrical type potential, and this is equal to divided by r.
01:05
So here, e, the charge of the electron, is just equal to minus 1 .6 times 10 per negative 19 column, and a is just equal to 1 over 4 pi at from 0 .0.
01:30
And this is equal to 8 .99 times 10 power 9 newton meter squared per colon squared.
01:43
So now here for n just equal to 1.
01:47
So this is r top 1 and here r top 1 just equal to 0 .0529 times 10 power negative 9 times one weird...
