Answer

Brief Explanations:

Arsenic (As) has an atomic number of 33. Its electron - configuration is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}3d^{10}4s^{2}4p^{3}$. The 3d sub - shell has 5 orbitals and can hold 10 electrons, which is completely filled in As. The 4s sub - shell has 1 orbital and can hold 2 electrons, which is also completely filled. The 4p sub - shell has 3 orbitals and can hold 6 electrons, but As has only 3 electrons in the 4p sub - shell, so it is partially filled.

Answer:

The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.
