Homework Statement
In a gas of hydrogen under normal conditions, the interatomic spacing is 1.56 × 10^−8 m . Assume the gas is made of atomic, not molecular, hydrogen. For what n-value of the hydrogen atoms is the size of the atom comparable to the interatomic spacing?The value of h bar is 1.05457 × 10^−34 J · s, the Bohr radius is 5.29177 × 10^−11 m , and the Rydberg constant for hydrogen is 1.09735 × 10^7 m−1 .
Homework Equations
r= n^2 hbar^2 / Z k q^2 m
n = energy level
Z=number of protons
hbar = Planck's /2/pi
k = Coulombs Constant
q = charge of electron
m = mass
The Attempt at a Solution
Please don't roast me, but i tried using the only equation I know that has both r and n in it. I plugged in my values and got the wrong answer ( 17.18) . Is there another equation that can be applied to correctly solve this problem? Again, I really have no knowledge of questions in this field. Thanks!
