If the question is an attempt to ask "How many orbitals are there with principal quantum number n = 2", then 4 orbitals which can hold a total of 8 electrons.
4 orbitals. when n = 2 there are l= 0 and l =1. when l= 0 we have one orbital and when l = 1 there are 3 orbitals . So 4 total
The second shell has s and p subshells. The s subshell has only an s orbital. The p subshell has px, py and pz orbitals. Thus, the second shell contains a total of 4 orbitals.

Sulfur has two electrons in the 1s orbital, two electrons in the 2s orbital, and 6electrons in the 2 p orbitals. The electrons are part of the first and second energy levels, the electron core. The next energy level, the last one, is the outermost energy which comprises the valence shell.
Your question reveals a common confusion between orbitals and shells. Chlorine has three electron shells: the first, second and third. The first shell has just the one orbital, the 1s The second shell has two sub-shells, the 2s and the 2p. There are three p orbitals in the 2p sub-shell. Each orbital can hold two electrons, so there are eight electrons maximum in the second shell. The third shell likewise has two sub-shells, the 3s and the 3p, but the 3p is not completely filled, leaving room for one more electron. When chlorine gains this electron it will become a Cl- ion. This is summed up in the electron configuration 1s22s22p63s23p5.
5 electrons in p orbitals in the outer shell. Cl has an electronic configuration of [Ne] 3s2, 3p5 In level 2 there a further 6 electrons in p orbitals making 11 electrons in total occupying p orbitals
Nitrogen has 5 valence electrons. Valence electrons are the electrons that are found in the outer most shell of an atom, and are consequently the electrons that move from atom to atom in the formation of compounds. The reason for this is a result of the electron configuration. A nitrogen atom has 3 orbitals; the 1s orbital, the 2s orbital, and the 2p orbital. In this case, the 2s and 2p orbitals are the valence orbitals, as they have the electrons with the most energy. With 7 protons, a neutral nitrogen atom has 7 electrons. The s orbitals can only hold 2 electrons, and the p orbitals can hold up to 6 electrons. The 1s orbital is filled first, leaving five electrons, then the 2s orbital is filled, leaving 3 electrons, and then these remaining electrons fill the 2p orbital halfway. There are a total of 5 electrons in the 2s and 2p orbitals, and since these orbitals have the most energy, there are 5 valence electrons.
Sulfur has three electron orbitals. The first orbital contains 2 electrons, the second contains 8 and the third contains 6.
8 electrons can be accommodated in the 2nd shell (aka 2nd energy level). 2 in the 2s orbital and 6 in the 2p orbitals.

There are 36 types of orbitals in the sixth shell.
3 shells; 2 electrons in the first shell, 8 in the second shell and 8 in the third shell.
2. the 2s ordital and 2p
Krypton is a noble gas and hence has stable electronic configuration. Its valence shell configuration is 4s2 4p6 . Therefore, it has 1-s and 3-p full orbitals in its valence shell.
The 3rd shell can contain 18 electrons. The elements that have a 3rd shell as the outer shell are the the elements in period 3, where the 3s and 3p orbitals are filled to a maximum of 8 electrons. The 3d orbitals are filled in the 4th period in the transition elements.
There are three p orbitals in all levels 2 and above. these are the px, py and pz orbitals, the (suffix is the direction - px lies along the x axis). In the 5th level they will be 5px, 5py, 5pz
The third energy level contains one s orbital and three p orbitals.
there are 7 orbitals in the f sublevel.
Only four in each have been observed.
S sub-shell has only one orbital. So, the 2nd energy level has only one s orbital.
