10 electrons.
The angular momentum quantum number is l (small L). This quantum number is dependant on the principal quantum number, and has values, 0 1,2 ..(n-1), where each value of n refers to a subshell known to chemists as follows
n= 0, s orbital; n=1, p orbital; n= 2, d orbital; n= 3, f orbital.
So we are looking at the d orbitals.
There are five d orbitals, with magnetic quantum numbers running from -l to +l, that is -2, -1, 0, +1, +2
Each of these can hold 2 electrons (with spin quantum numbers -1/2, +1/2)
So we have 10 electrons that can have pricipal quantum numbers of 4 and angular monmentum quantum number of 2.

Why their no rational numbers closest to 0?
The answer depends on who they are that possess rational numbers.
When an atom has one or more extra electrons it will have a positive charge?
No. Electrons possess a negative charge, therefore an atom with an excess of electrons will have an overall negative charge.
Do negative numbers possess inherent value?
Yes, as much as positive numbers do.
What is the same number of possess of atom of one type of element?
protons and electrons
What is the maximum number of electrons that a representative element can possess?
8 so then it is an Octet.
