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.
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 is atomic number 33 and has 5 valence electrons. Method for finding valence electrons: All electrons are arranged in orbital shells. The inner shell can hold up to 2 electrons. The second shell holds up to 8. The third shell holds up to 18 and so on. The outer shell holds the valence electrons. To find out how many there are, count the electrons in the inner shells 2+8+18 = 28, in this case, and subtract them from the 33 electrons that Arsenic has: 33 - 28 = 5 valence electrons.
Five valence electrons. They all exhibit different oxidation numbers too!!!!
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
Arsenic has 5 [valence electrons] in them.

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
Nitrogen, Phosphorus, Arsenic, Antimony, and Bismuth all have 5 valence electrons
