The quantum mechanical model determines the allowed energies an electron can have and how likely it is to find the electron in various locations around the nucleus of an atom.
You are watching: How many orbitals are in 4p sublevel
Each energy sublevel corresponds to an orbital of a different shape, which describes where the electron is likely to be found
How many orbitals are in the following sublevels? a. 3p sublevel b. 2s sublevel c. 4p sublevel d. 3d sublevel e. 4f sublevel
a. there are 3 orbitals in 3p b. there is 1 orbital in 2s c. there are 3 orbitals in 4p d. there are 5 orbitals in 3d e. there are 7 orbitals in 4f when n = 1, it means it has one shell. the first shell is s, and s shells have one orbital when n=2 (2 shells), there are s and p shells, so s shells still have one orbital, but p shells have 3 orbitals. as u can see when n=3, d shells show up, it will have 5 orbitals and when n=4, f shells show up, and it will have 7 orbitals.
Use the aufbau diagram to arrange the following sublevels in order of decreasing energy: 2p, 4s, 3s, 3d, and 3p.
Why do the actual electron configurations for some elements differ from those assigned using the aufbau principle?
Some actual electron configurations differ from those assigned using the aufbau principle because half-filled sublevels are not as stable as filled sublevels, but they are more stable than other configurations.
Why does one electron in a potassium atom go into the fourth energy level instead of squeezing into the third energy level along with the eight already there?
