The correct electron configuration would be 3d5 as each orbital in the 3d sublevel can hold up to 2 electrons, and we have 5 electrons to place in this sublevel.
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.
The elements in period 4 that have electrons in the 3d sublevel are elements 21 - 36. Refer to the Related Links for a printable periodic table that includes electron configurations.

Vanadium (V) contains 5 electrons in its 3d orbitals.
In the ground state of a chromium atom (atomic number 24), the electron configuration is [Ar] 3d^5 4s^1, with 5 electrons in the 3d sublevel and 1 electron in the 4s sublevel. This configuration is due to the stability achieved by half-filling the 3d sublevel before completely filling the 4s sublevel.
Al, Si, P, S, Cl and Ar have 1, 2, 3, 4, 5 and 6 electrons respectively in the 3p (valence orbitals). However all elements after Argon have completely filled 3p orbitals though 3p is not the valence orbital.
The elements in period 4 that have electrons in the 3d sublevel are elements 21 - 36. Refer to the Related Links for a printable periodic table that includes electron configurations.
the total electron distribution in such an atom is 1s--2 2s--2 2p--6 3s--2 3p--5 so, total number of electrons comes out to be 17. so, the element is chlorine. symbol is Cl.

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
