Which of the following is the property of Rydberg constant?

Which of the following is the property of Rydberg constant?
  1. It is universal constant
  2. It is same for all hydrogen like atom
  3. It depends on the atomic number of the atom
  4. It depends on the mass number of the atom

Solution

We know that, Rydberg constant, $R=\frac{e^4 m}{8 \varepsilon_0^2 h^3 c}=1.09 \times 10^7 \mathrm{~m}^{-1}$ It remains constant for a atom, like hydrogen or hydrogen like atom.
