Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If an electron transitions from n=4 to n=2, calculate the frequency of the emitted photon and its associated energy using E=hf and the speed of light.

💡 Hint: You will need to calculate the energy of the photon before finding frequency.

Challenge 2 Hard

Discuss how Bohr's model couldn't accurately describe orbitals in more complex atoms and what model succeeded it.

💡 Hint: Consider how electrons interact in a multi-electron system.
