5 sub-orbitals with (max.) two electrons in each, so 10 in total. This is also true for 4d and 5d orbitals

0, they only start appearing in n = 4 orbitals.
The third energy level contains one s orbital and three p orbitals.
When n=3 you can have s, p and d orbitals.

This is the principal quantum number, n.

There is no single quantum number that will tell you the size of an atom.The best answer to the question is the principal quantum number n, though it isn't a particularly good answer. While in general atoms with high maximum n tend to be larger than atoms with low maximum n, this doesn't always hold true. For example, chlorine (highest n value 3) is actually slightly smaller than lithium (highest n value 2).Also, two atoms with the same maximum n can be significantly different in size.
The principal quantum number n = 3 and the azimuthal or orbital angular momentum quantum number would be l =1 .l = 1

Its Principal quantum no is 2
n=2 has 3 2p orbitals.
The "formula" is n2 - so for principal quantum number 4 there are 16 orbitals, correspnding to one X s orital, three X p orbitals, five X d orbitals, seven X f orbitals.
For fun, let's give them numbers instead of letters, and call s "0", p "1", d "2", and f "3".Then the number of distinct orbitals for any given principal quantum number (which is a more precise way of the concept you meant when you said "energy level") is twice the number plus 1... though the principal quantum number must be higher than the numbers we just gave the orbitals in order for there to be any at all (there aren't any 1p orbitals, for example). For principal quantum number of at least four, there are 1 s orbital, 3 p orbitals, 5 d orbitals, and 7 f orbitals. If we call the four quantum numbers n, l, m, and s, where n is the principal quantum number, l is the azimuthal quantum number, m is the magnetic quantum number, and s is the spin quantum number, the permissible values are: n - any integer such that 0 < n ("shell") l - any integer such that 0 <= l < n (orbital "type" - s, p ,d ,f, g, h, i, etc.) m - any integer such that -l <= m <= l (individual orbitals of type l) s - -1/2 or +1/2 (electron "spin")
secondary quantum numberI don't think it is a number, but it could be referring to the Orbitals, being S, P, D, and F. Each orbital is a specific shape and the orbitals are determined in blocks on the Periodic Table. The energy, or Quantum Number would go in front, such as 4p, which means the principal quantum number or energy level is 4 and the orbital shape is p. Hope this helps
Each shell has a total of n2 orbitals, where n is the principal quantum number. For N shells the total orbitals is therefore :- N2 + (N-1)2 + (N-2)2 +....+1
This is the principal quantum number, n.
