WebNov 6, 2015 · Nov 6, 2015 The electron configuration for the As3− ion is [Ar]3d104s24p6. Explanation: Arsenic, As, has atomic number 33, which is the number of protons in the nuclei of its atoms. A neutral As atom would also have 33 electrons. The electron configuration of a neutral arsenic atom is [Ar]3d104s24p3. WebArsenic is the 33rd element of the periodic table so its atomic number is 33. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, an arsenic atom has thirty-three protons and thirty-three electrons.
