3 shells; 2 electrons in the first shell, 8 in the second shell and 8 in the third shell.
There are 36 types of orbitals in the sixth shell.
Atoms of elements in the third period are less subject to destabilization from additional electron-electron repulsions.The third shell contains d orbitals that are relatively close in energy to 3s and 3p orbitals and provide an allowed energy state for extra electrons.Atoms of elements in the third period have the space and available orbitals to accommodate extra electrons.
Thus the total number of atomic orbitals in the fourth energy level of an atom is 16.

3 shells; 2 electrons in the first shell, 8 in the second shell and 8 in the third shell.
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
There are 36 types of orbitals in the sixth shell.
the first shell (the K shell) can only contain a maximum of two electrons, as it consists of just an s orbitalthe second shell (the L shell) can contain a maximum of eight electrons, as it consists of an s orbital and three p orbitalsthe third shell (the M shell) can contain a maximum of eighteen electrons, as it consists of an s orbital, three p orbitals, and five d orbitalsthe fourth shell (the N shell) can contain a maximum of thirty two electrons, as it consists of an s orbital, three p orbitals, five d orbitals, and seven f orbitalsthe fifth shell (the O shell) can contain a maximum of fifty electrons, as it consists of an s orbital, three p orbitals, five d orbitals, seven f orbitals, and nine g orbitalsetc.
There is one s orbital and three p orbitals and five d orbitals in the third energy level.
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.
Atoms of elements in the third period are less subject to destabilization from additional electron-electron repulsions.The third shell contains d orbitals that are relatively close in energy to 3s and 3p orbitals and provide an allowed energy state for extra electrons.Atoms of elements in the third period have the space and available orbitals to accommodate extra electrons.
The 3rd period contains 2 of the 3 orbitals for the third sublevel. It has the s and p orbitals in it.
helium has 2 electrons in its 1st orbital. It doesn't have 2nd or 3rd orbitals.
The third energy level contains one s orbital and three p orbitals.
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.
Thus the total number of atomic orbitals in the fourth energy level of an atom is 16.
