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

Atomic orbitals are regions in space where electrons are likely to be found. The sizes of atomic orbitals increase as the principal quantum number (n) increases. The energy of atomic orbitals increases with increasing principal quantum number and decreasing distance from the nucleus. The shape of atomic orbitals is determined by the angular momentum quantum number (l).
In the context of atomic orbitals, the 2d orbital does not exist. The electron orbitals in an atom are defined by three quantum numbers: principal quantum number (n), angular momentum quantum number (l), and magnetic quantum number (m). The angular momentum quantum number (l) can take values of 0 to (n-1), meaning the d orbitals start at l=2, corresponding to the 3d orbitals.
1p is not a valid orbital designation according to the rules for assigning quantum numbers to atomic orbitals. Orbitals are defined using the principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m), and spin quantum number (s). The orbital with n=1 and l=1 is designated as 2p, not 1p.
Atomic orbitals do not have an exact size, but rather a region where there is a high probability of finding an electron. The size and shape of an atomic orbital depend on the quantum numbers that describe it, such as the principal quantum number.
The atomic states with principal quantum number 4 can have orbital angular momentum quantum numbers from -4 to 4. Hence there are 9 possible values of the orbital angular momentum quantum number. Each electron can have spin +1/2 or -1/2, so each of the states specified by a given orbital angular momentum quantum number can have at most two electrons in the state without violating Pauli's exclusion principle. So, in sum, there are 18 possible states for an electron with principal quantum number 4.

There are a total of three p orbitals for an atom with principal quantum number n = 2: px, py, and pz. These orbitals are oriented along the x, y, and z axes.
To determine the general shape of an orbital, you need the quantum numbers associated with the electron, particularly the principal quantum number (n) and the azimuthal quantum number (l). The principal quantum number indicates the energy level and size of the orbital, while the azimuthal quantum number defines the shape (s, p, d, f). The values of l correspond to specific shapes: s orbitals are spherical, p orbitals are dumbbell-shaped, and d orbitals have more complex geometries. Additionally, the magnetic quantum number (m_l) can provide information about the orientation of the orbital within a given shape.
The principal energy level that consists of one s orbital and three p orbitals has a quantum number of 2. The s orbital is part of the first principal energy level (n=1) and the p orbitals are part of the second principal energy level (n=2).
The principal quantum number of the first d subshell is 3. In the case of d orbitals, they start appearing in the n=3 energy level.
In the context of atomic orbitals, the 2d orbital does not exist. The electron orbitals in an atom are defined by three quantum numbers: principal quantum number (n), angular momentum quantum number (l), and magnetic quantum number (m). The angular momentum quantum number (l) can take values of 0 to (n-1), meaning the d orbitals start at l=2, corresponding to the 3d 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")
1p is not a valid orbital designation according to the rules for assigning quantum numbers to atomic orbitals. Orbitals are defined using the principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m), and spin quantum number (s). The orbital with n=1 and l=1 is designated as 2p, not 1p.
