### Rydberg Constant

What is the significance of this value and is this only applied to H-atoms?

The Rydberg constant is used for the equation that calculates the energy required for each energy level in a H-atom:
$E = (h*R)/n$

The equation En= -hR/n^2 is used to calculate the empirical formula for only the H-atom. This is because as a neutral atom it only has one electron. Therefore on the nucleus affects the electron rather than other electrons influencing it too because electrons repel each other. This is why this equation only works for the H-atom or for He^+1 for example.
