Bohr model hydrogen potential energy

Click For Summary
SUMMARY

The potential energy of the hydrogen atom in the n=11 state using the Bohr model is calculated using the formula U = -kZe²/r. In this case, the constants used are k = 8.99e9 N m²/C², e = 1.6e-19 C, and the radius for the n=11 state is required for accurate computation. The potential energy for the ground state was incorrectly applied, yielding -27.2 eV, which is not valid for n=11. The correct radius for n=11 must be used to determine the potential energy accurately.

PREREQUISITES
  • Understanding of the Bohr model of the atom
  • Familiarity with potential energy equations in electrostatics
  • Knowledge of constants such as Coulomb's constant (k) and elementary charge (e)
  • Ability to calculate energy in electron volts (eV)
NEXT STEPS
  • Calculate the radius for the n=11 state in the Bohr model
  • Recompute potential energy using U = -kZe²/r for n=11
  • Explore the implications of potential energy in quantum mechanics
  • Study the differences between classical and quantum mechanical models of the atom
USEFUL FOR

Students studying quantum mechanics, physics educators, and anyone interested in atomic structure and energy calculations using the Bohr model.

You have used r for the ground state (n=1), and have found the potential energy of the ground state.

You'll need to use r for the n=11 state.
