The chemical element arsenic, or As, is in group 15, period 4. Thus its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3. Since its outermost shell is 4, arsenic has 5 valence electrons.
Arsenic has a mass number of 33 with an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3. This means that there are 3 valence electrons.

Arsenic (As) has five valence electrons, as it is located in group 15 of the periodic table. In AsCl, arsenic forms a covalent bond with chlorine (Cl), which has seven valence electrons. The minimum number of electrons in the valence shell of arsenic in this compound would still be five, as it does not lose any of its valence electrons despite forming bonds. Therefore, As would have five electrons in its valence shell in AsCl.

As: Arsenic 33
In arsenic triiodide (AsI3), arsenic (As) typically has five valence electrons, while each iodine (I) atom has seven valence electrons. In the molecule, arsenic forms three covalent bonds with three iodine atoms, using three of its valence electrons. This leaves arsenic with two unshared electrons, which can be considered as one lone pair. Therefore, there is one ion pair of electrons associated with the arsenic in AsI3.
Arsenic is in group 15, it can lose 5 valence electrons or gain 3 valence electrons to achieve the octet. Its minimum oxidation state we can predict as being -3, and its maximum as +5
What kind of question is that lol I don't even know that and I just studyed that last semester lol
