for the case of n=4 the available orbitals include 1s 3p and 5d, a total of 9 electron orbitals which can occupy 18 electrons. There are 18 elements in the 4th row which coincides with the 9 available orbitals.

n1 has 1 n2 has 4
There are 4 orbitals in H2O , one s and 3 p
no because f orbitals are not energetically available until the n=4 quantum state
16 orbitals in the 4th energy level. One s orbital, three p orbitals, five d orbitals, seven f orbitals Elements where the 4th principal energy level are filled are:- period 4 4s and 4p (starting with potassium) period 5 4d starting with Yttrium Lanthanides 4f starting with cerium
principal energy level (n)= 3 Number of orbitals per level(n2)= 9 it equals 9 because it is n2 (32=9) n=1. 1 orbital n=2. 4 orbitals n=3. 9 orbitals n=4. 16 orbitals n=5. 25 orbitals n=6. 36 orbitalsn=7. 49 orbitals
All p sublevels contain three orbitals, including the 4p sublevel.
