Spectra and the Bohr Model An electron is hit with a photon that does not have enough energy to cause a full energy level change. What happens in the atom? The electron releases an extra photon and goes into the nucleus, causing an explosion. The electron keeps the same amount of energy and doesn't move. The electron still absorbs the light and jumps higher anyway. Back Reload Home Profile Menu

If an electron is hit by a photon with insufficient energy, it stays in its current energy level and doesn't move.

Solución

In the Bohr model of the atom, electrons occupy specific energy levels. For an electron to move from a lower to a higher energy level, it must absorb a photon with energy exactly equal to the difference between those two levels. **If an electron is hit with a photon that does not have enough energy to cause a full energy level change, the following occurs:** **The electron retains its current energy level and does not move to a higher energy state.** The photon is not absorbed since its energy is insufficient to bridge the gap between the electron's current energy level and the next one. Consequently, the electron remains in its original orbit, and the photon continues without interacting with the electron. **Correct Answer:** The electron keeps the same amount of energy and doesn’t move.

Mind Expander

When an electron is hit with a photon that lacks sufficient energy to cause a full energy level change, it simply keeps the same amount of energy and remains in its original orbit. That's right! The photon doesn't get absorbed, and the electron doesn't get excited to a higher energy level. Instead, it carries on with its usual business, like a cat ignoring a laser pointer. In terms of real-world application, this principle is crucial for understanding how lasers work or why we observe certain colors in light. For instance, if you shine light with energies that don't match the required energy level changes, you won't see any electron transitions—hence no laser activity! It's all about the right energy match for the electron dance party!
