Class 12 Physics simulations · Atoms

Bohr’s atomic model

Choose an orbit and calculate the photon released in a transition to the ground state.

Open the simulation

What to notice

Higher levels are farther apart in radius but closer together in energy.

Key relation

Eₙ = −13.6 Z² / n² eV

Try this

Raise n and compare the n → 1 photon energy.

What you can change

• Excited energy level: 2 to 5
• Atomic number (H-like): 1 to 3
