Calculate the orbital radius of the hydrogen atom for the first principal quantum number. Use the general expression given in the test to calculate this value. (Hint: Quantum numbers are not significant digits and should not be counted as such in determining your final answer. Thus, this answer should have 2 significant digits.)

That was super confusing. Do you by any chance know how to do the formula and can explain it?

anonymous · Answer

$$a _{0} =\frac{ h ^{2} }{ 4\pi ^{2}mke ^{2}} $$

use this formula.. 
 
h planck constant
m mass of electron
k coulomb constant
e charge of electron

Truley and honestly with you I have absolutely no clue what any of that is. I'm in an early grad school and my "teacher" doesn't know physics so I'm sliding by in class on online school work. The "lessons" haven't even taught me that -____-
