p-sublevel

Explanation:

Arsenic is an element on the fifth group on the periodic table. Other elements in the group are Nitrogen, Phosphorus, Antimony and Bismuth.

The electronic configuration of Arsenic is given as:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³

It has an atomic number of 33:

Number of electron containing orbitals = 4

it has four energy levels. It also belongs to the fourth period on the periodic table.

How many of the orbitals are completely filled = 3

The inner orbitals are completely filled i.e the first 3 orbitals.

Number of unpaired electrons = 3

They can be found in the 4p³ sublevel.

Sublevel where unpaired electrons are located = p-sublevel
