The principle quantum number has the symbol n. It tells which energy level an electron is in. The values include one and beyond. The lower the number, the closer the energy level is to the atom's nucleus. Multiple electrons can be in the same energy level. Also, n2 is the total number of orbitals that can exist within an energy level n. For example, level 1 has 1 orbital (s=1). Level 2 has 4 orbitals (s=1 + p=3). Level 3 has 9 orbitals (s=1 + p=3 + d=5). Level 4 has 16 orbitals (s=1 + p=3 + d=5 + f=7). Each letter, s, p, d, and f stands for a type of sublevel that contains a certain number of orbitals.

The maximum number of electrons in a period with a principle quantum number of 4 is?
The maximum number of electrons in a period with a principle quantum number of 4 is 32. Each period corresponds to a principal quantum number, and the number of electrons in a period can be calculated using the formula 2n^2, where n is the principal quantum number. In this case, for n=4, 2(4)^2 = 32.

Is Magnetic quantum number ever larger than the principle quantum number?
No, for any given electron, the principle quantum number will be larger. For example, a second shell, p-subshell electron will have the quantum numbers {2, 1, ml, ms} where mlcan be -1, 0, or 1 and, as always, ms can be ½ or -½. The largest ml can be is +1, which is smaller than the principle quantum number, 2.

How many quantum number are required to specify a single atomic orbital?
Four quantum numbers are required to completely specify a single atomic orbital: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m), and spin quantum number (s). These numbers describe the size, shape, orientation, and spin of the atomic orbital, respectively.

Maximum of 32 electrons.
What does a quantum number describe?
n is the first quantum number. It is the principle quantum number. It refers to what energy level it is and will be one greater than the number of nodes in the orbital. l is the second quantum number. It is the angular momentum quantum number and refers to the shape of the orbital. ml is the third quantum number. It is the magnetic quantum number and it refers to the orientation of the orbital. ms is the fourth quantum number. It is the spin quantum number and refers to the magnetic character of the orbital.
How is the principal quantum number symbolized?
The principal quantum number is symbolized as "n" in the context of quantum mechanics. It represents the energy level of an electron in an atom and determines the average distance of the electron from the nucleus.
