the lowest energy level to allow f orbitals is the fourth energy level
The 4th energy level is the lowest that contains and f sub-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.
1 type s orbital → max 2 electrons 3 type p orbitals → max 6 electrons 5 type d orbitals → max 10 electrons 7 type f orbitals → max 14 electrons 9 type g orbitals → max 18 electrons [edit] Aufbau principle In the ground state of an atom (the condition in which it is ordinarily found), the electron configuration generally follows the Aufbau principle. According to this principle, electrons enter into states in order of the states' increasing energy; i.e., the first electron goes into the lowest-energy state, the second into the next lowest, and so on. A pair of electrons with identical spins has slightly less energy than a pair of electrons with opposite spins. Since two electrons in the same orbital must have opposite spins, this causes electrons to prefer to occupy different orbitals. This preference manifests itself if a subshell with l > 0 (one that contains more than one orbital) is less than full. For instance, if a p subshell contains four electrons, two electrons will be forced to occupy one orbital, but the other two electrons will occupy both of the other orbitals, and their spins will be equal. This phenomenon is called Hund's rule. Hund's rules Hund's rules, (occasionally called the "bus seat rule") refer to a simple set of rules used to determine which is the term symbol that corresponds to the ground state of a multi-electron atom. They are named in honour of Friedrich Hund who contributed Hund's Rule, rule two as listed here. The four rules are: 1. Electrons can occupy energy levels only above the 2s orbital total orbital. 2. The term with maximum multiplicity (maximum ) has the lowest energy level. 3. For a given multiplicity, the term with the largest value of has the lowest energy in an orbital. 4. For atoms with less than half-filled shells, the level with the lowest value of lies lowest in energy. Otherwise, if the outermost shell is more than half-filled, the term with highest value of is the one with the lowest energy.
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 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
The s orbital has the lowest energy level.
Aufbau principle
It is based on many factors, but the easiest to understand is ENERGY. The orbitals in which the electron has the lowest energy are filled FIRST.
Electrons will occupy orbitals having the lowest energy first, and then in order of increasing energy.
ground state
The 4th energy level is the lowest that contains and f sub-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
