no
3f
3f can not exist by the Aufbau principle, quantum mechanics and Hunds rules. In level one there is only 1s In level 2 there is 2s and 2p In level 3 there is 3s, 3p and 3d Only in level 4 and beyond is there an f shell. In level 4 there is 4s, 4p, 4d and 4f. The 4f can hold up to 14 electrons.

no because f orbitals are not energetically available until the n=4 quantum state
There can be a maximum of 14 electrons in any "f" orbital. However, the 3f orbital does not exist. f orbitals are only found in quantum energy level 4 and above.
The F sublevel has a total of seven orbitals, each capable of holding a maximum of two electrons. Therefore, the maximum number of electrons that can exist in the F sublevel is 14 (7 orbitals × 2 electrons per orbital).
There are 9 orbitals in a g sublevel. (there is 1 in an s sublevel, 3 in a p sublevel, 5 in a d sublevel, 7 in an f sublevel, 9 in a g sublevel, 11 in an h sublevel, etc.)
-3f - 14 = 1 -3f = 1+14 -3f = 15 f = -5

Adrenaline is the 3F hormone.
The 4s sublevel is completed when it contains a total of two electrons. In the context of electron configuration, this sublevel is filled before the 3d sublevel, according to the Aufbau principle. Thus, the 4s sublevel is filled before the 3d sublevel begins to receive electrons.
