For nuclear notation, the mass number of the isotope goes on top and the atomic number goes on the bottom. Protons Electrons Neutrons Nuclei ΑΙ U A13+ S2 SO2 SO32- NHA 36 Electrons = Atomic Number + 2 extra electrons (hence the 2-) The chemical symbol for Selenium is Se . You need the atomic number to find the amount of protons and/or electrons, unless you have the amount of neutrons and the atomic mass, in which case you can simply subtract the amount of neutrons from the atomic mass, leaving the amount of protons in the atom. Origin of Name: From the Latin silicus, meaning flint: Date and Place of Discovery: In 1824 in Stockholm, Sweden: Discovered by: Jons Jakob Berzelius: Common Compounds: Silicon dioxide (SiO 2); Silicon carbide (SiC); Sodium silicate (Na 2 SiO 3); Silicon tetrachloride (SiCl 4); Interesting facts    Boiling Point Property release not required. Neutron Number and Mass Number of Arsenic Mass numbers of typical isotopes of Arsenic are 75. Determine the number of protons, neutrons, and electrons in each isotope. For the Periodic Table, the Atomic Number is on top and the average atomic mass is on the bottom. These are easily rubbed off of some atoms, creating "static electricity" Arsenic is a chemical element with atomic number 33 which means there are 33 protons and 33 electrons in the atomic structure.    Metalloids the Terms and Conditions. The third part of the atom is the neutron. What is Arsenic. The chemical symbol for Arsenic is As.. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic, which is extremely toxic, is used as a dopant in semiconductors. Diagram of the nuclear composition and electron configuration of an atom of arsenic-75 (atomic number: 33), the most common isotope of this element. The chemical symbol for Arsenic is As.
