3d
The lowest energy level that has F orbitals is the fourth energy level. The Atomic orbital of any atom only contains 2 electrons.
the lowest energy level to allow f orbitals is the fourth energy level
Each main energy level (1 to 7) has at least an s-orbital, p-orbitals are possible from the second level onwards (2 to 7) d-orbitals from 4th level f-orbitals from 6th level
The energy level closest to the nucleus is the 1s orbital and can hold 2 electrons as do all s orbitals. Every electron orbital has a distinct shape and number. The 1s orbital has the same shape the 2s orbital and the 3s orbital and so forth. There are other orbital shapes such as p, d, and f. Regardless of the number or level of the orbital, all p orbitals are the same shape and all d orbitals are the same shape. Orbitals differ in distance from the nucleus and the distance is indicated by the number before the orbital shape.
The lowest energy level that contains d orbitals is the third energy level. Within the third energy level, starting with the 3d sublevel, the d orbitals become available.
There can be 10 electrons in a D orbital
The number of possible different orbital shapes for the third energy level is 3. For n equals 4 the number of possible orbital shape is 4.
after the s orbital of the next highest energy level
Each main energy level (1 to 7) has at least an s-orbital, p-orbitals are possible from the second level onwards (2 to 7) d-orbitals from 4th level f-orbitals from 6th level
There are five d orbitals in one energy level. These orbitals are designated as dxy, dyz, dxz, dz2, and dx2-y2. Each d orbital can hold a maximum of 2 electrons.
The principal energy level is three, so there are three sublevels: 3s, 3p, and 3d. S,P and D
There is one s orbital and three p orbitals and five d orbitals in the third energy level.
