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.
it gives us the energy state of electron which further help to know whether electron is closer or farther from nucleus
This was introduced by Bohr. it is known as main Energy level of an Electron.
A principle quantum number is always symbolized by a lowercase letter "n." The function of a principle quantum number is to show positive integer values in an equation.
Primary quantum number is n.
There are several different quantum numbers for a given atom (principle quantum number, the angular quantum number, the magnetic quantum number, the spin quantum number, etc) .I assume you are looking for the Principle Quantum number, n, which is equal to the row (period) in the period table in which the element is situated.For helium, the principle quantum number is 1.i.e. n = 1As another example; the principle quantum number for potassium (K), n = 4.
3s has a principle quantum number of n=3 5s has a principle quantum number of n=5

Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
n (principle quantum number) = 4 l (angular momentum quantum number) = 2 ml (magnetic quantum number) = -2, -1, 0, 1, or 2 ms (spin quantum number) = +1/2 or -1/2

For a principle quantum number 3, there are three possible sub-shells. These are 3s, 3p, 3d. Azimuthal quantum no. is less than principle quantum number. There for 3s it is 0, for 3p it is 1, for 3d it is 2.
3s has a principle quantum number of n=3 5s has a principle quantum number of n=5
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.
it is the principle quantum number
The first three quantum numbers (principle, angular momentum, magnetic) are all whole numbers. The last quantum number (spin) is either ½ or -½.

I Absolutely have NO clue but I'm still posting this up :P
Period number basically indicates the total number of shells avaiable and hence it is equal to the principal quantum number.
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.
