How does the Bohr Model Calculator work?

Enter principal quantum number (n) Then: The calculator finds electron radius, energy, and transition frequencies Then: Results show orbital properties.

Can you give an example of how to use the Bohr Model Calculator?

Example: Input n = 2 (first excited state) gives a result of r = 4 × Bohr radius ≈ 212 pm, E = -3.4 eV (Relative to n=∞).

Is the Bohr Model Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Bohr Model Calculator?

Our Bohr Model Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
