Quantum Mechanics: What are the electron energies? Bohr Model Quantum Mechanical Model (High P.E.) 3d 3p n=3 3s 2p n=2 2s n=1 1s (Low P.E.) Factors that affect electron energies: Orbital Size p+ e- Hydrogen Atom p+ 1s orbital e- Hydrogen Atom Remove the electron and compare!
For an electron, what is the number of possible l values if the principal quantum number is n = 2? What energy has an electron on the last level occupied on a nickel's atom? What is the energy of the electron in the ground state of a He+ ion?
TheBohr modelis no longer thought to be accurate, particularly as it pertains to how the electrons orbit the nucleus. While the model can still be useful in understanding the basics of electron distribution and different energy levels, it fails to consider the complexity of that distribution and...
If an atom absorbs some energy, an electron in an orbital close to the nucleus (a lower energy level) will jump to an orbital that is farther away from the nucleus (a higher energy level). The atom is now said to be excited. This excitement generally will not last very long, and ...
