Bohr orbit radius
$$r = \frac{4\cdot \pi\cdot \varepsilon0\cdot n^{2}\cdot \hbar}{m\cdot e^{2}}$$
r - radius
ε0 - permittivity constant
n - quantum number
ℏ - small Planck constant
m - mass
e - electron charge
ε0 - permittivity constant
n - quantum number
ℏ - small Planck constant
m - mass
e - electron charge
