If it is in row 4 (4th period) it has 4 energy levels occupies. In the 2nd column (group 2A) it has 2 valence electrons. You ask how many orbitals it has. It has s and p orbitals. Is that what you mean? The configuration is 1s2 2s2 2p6 3s2 3p6 4s2 so there are 3 s orbitals and 6 p orbitals for a total of 9 orbitals.

There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
All p sublevels contain three orbitals, including the 4p sublevel.
There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
1st energy has 1 sublevel -- 1 orbital -- 2 electrons 2nd energy level has 2 sublevels -- 4 orbitals -- 8 e- 3rd energy level has 3 sublevels -- 9 orbitals -- 18 e- 4th energy level has 4 sublevels -- 16 orbitals -- 32 e- Notice the pattern? number of orbitals = energy level squared Number of electrons = 2x number of orbitals

There are 8 sublevels, or types of orbitals in the 8th energy level. They would be s, p, d,f, g, h, i,j.
There are four energy sublevels in the fourth energy levels: 4s, 4p, 4d, and 4f.
There are five sublevels in the fifth energy level: 5s, 5p, 5d, 5f, and 5g.
There are 2, 6 and 10 electrons in the 3s (1 suborbital), 3p (with 3 suborbitals: 3px, 3py, 3pz) and 5 sub orbitals in the 3d orbital: this makes a total of 18 electrons in 9 suborbitals
