How many electrons are there in an f sublevel?

The f sublevel can hold a maximum of 14 electrons.

This is because the f sublevel consists of seven orbitals, and each orbital can hold up to 2 electrons. To understand this better, let’s break it down:

• Each sublevel is made up of a specific number of orbitals.
• The f sublevel has 7 orbitals, denoted as f_-3, f_-2, f_-1, f₀, f₊₁, f₊₂, and f₊₃.
• Since each orbital can hold 2 electrons (one with spin up and one with spin down), you multiply the number of orbitals by 2: 7 orbitals × 2 electrons/orbital = 14 electrons.

Thus, the f sublevel is capable of accommodating up to 14 electrons, which plays an important role in the electron configuration of elements in the actinide and lanthanide series of the periodic table.
