Radius of Bohr Atom Orbitals

  1. Mar 27, 2012 #1
    1. The problem statement, all variables and given/known data

    Given the numerical value of a0= 5.3X10^11m in the Bohr hydrogen atom, find the radius of the first five orbitals as well as the radius for n=100.

    2. Relevant equations

    Rn=a0 x n^2

    3. The attempt at a solution
    Could it be as simple as typing in for the third orbital 3 as n? Meaning the radius for the third orbital will be Rn= 5.3X10^11 x 3^2 = 4.77x10^12m ?

    welcome to PF, aisha1929

    and yes, it really is that simple :)

    one of the things about quantum physics and electron orbitals is that they are "quantized" meaning that there are specific values for which things can actually have. The electron can only be in one of those orbitals, it can't be orbiting the nucleus in, like, orbital shell 2.83 or shell 4.19, etc.

    things are stuck in discrete levels or directions or shells, etc.
