1 Answer
The complete electron for a neutral arsenic atom is:
Atomic number of the element arsenic is 33. It means one atom of arsenic has 33 protons in its nucleus. Atomic mass of arsenic is 74.92. It is found as solid at 20 ℃ temperature. Arsenic is a grey-appearing chemical element (atomic number 33, symbol As in the periodic table) also termed a metalloid. Arsenic can exist in a metallic state in three forms (yellow, black, and gray; with gray predominating) and in ionic forms. Atomic Number: 33. Atomic symbol: As. Atomic Weight: 74.9216. Electron affinity: -77 kJ/mol. Electron configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 3. Ionization energies: 947 kJ/mol. Atomic Number of Arsenic Arsenic is a chemical element with atomic number 33 which means there are 33 protons and 33 electrons in the atomic structure. The chemical symbol for Arsenic is As. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.

Its shorthand electron configuration is:
Explanation:
As is the chemical symbol for the element arsenic. Its atomic number is 33, which is the number of protons in the nuclei of its atoms. In a neutral atom, the number of electrons equals the number of protons, which means that neutral arsenic atoms have 33 electrons.
By using the Aufbau diagram (shown below) we can determine the full electron configuration for a neutral arsenic atom. Download movies torrentbit.
