When l = 3 (f-type orbitals), m l can have values of –3, –2, –1, 0, +1, +2, +3, and we can have seven 4f orbitals. Thus, we find a total of 16 orbitals in the n = 4 shell of an atom. Exercise \(\PageIndex{1}\)

Answer: Orbitals are the regions of space in which electrons are most likely to be found. Explanation: Each orbital is denoted by a number and a letter. The number denotes the energy level of the electron in the orbital. Thus 1 refers to the energy level closest to the nucleus; 2 refers to the next energy level further out, and so on.
For any atom, there are seven 7 f orbitals. The f -orbitals are unusual in that there are two sets of orbitals in common use. The first set is known as the general set, this page. The second set is the cubic set, this page and these might be appropriate to use if the atom is in a cubic environment, for instance.
p Orbitals. Only s orbitals are spherically symmetrical. As the value of l increases, the number of orbitals in a given subshell increases, and the shapes of the orbitals become more complex. Because the 2 p subshell has l = 1, with three values of ml (−1, 0, and +1), there are three 2 p orbitals.
14 Αυγ 2020 · Principal shells with n = 4 can have subshells with l = 3 and m l values of −3, −2, −1, 0, +1, +2, and +3. These subshells consist of seven f orbitals. Each f orbital has three nodal surfaces, so their shapes are complex.

The three different p orbitals within a given shell are oriented in space along mutually perpendicular directions, denoted p x, p y, and p z. As shown in Figure 1.6, the two lobes of each p orbital are separated by a region of zero electron density called a node.
