The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given. Accordingly, the number of protons, which is always equal to the number of electrons in a neutral atom, is also the atomic number. |-style="background-color:#cccc99" |85||Astatine||At||6, 17||[209.9871][5] |-style bgcolor="#c0ffff" |-style="background-color:#ffc0c0" Number of protons = 11. https://chemistry.fandom.com/wiki/List_of_elements_by_atomic_number?oldid=8359.
