Now let's check the facts about Thallium... Thallium Overview Thallium Valence Electrons 1,3 Atomic Number 81 ... Found in iron pyrites. Now we can look at the superscripts (which designate the number of electrons in each orbital). O.K. Since valence electrons are defined as the electrons that occupy the highest principal energy level of an atom, iron would have two valence electrons. (3) The polyatomic ions nitrate and azide are both tetraatomic entities. Atoms lose or gain electrons in order to become stable. 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 6.
