Selenium is a polyatomic, nonmetallic chalcogen with a large atom size (located in the period 4 along with potassium and bromine) and high polarizability, and is d-electron-rich (located in group 16).32 Because of these characteristics, selenium is a promising potential 1Department of Materials...
Fluorine has atomic number Z = 9, while bromine has Z = 35. Samanantar If we look here on the periodic table, it has an atomic mass number of 41, and its average atomic mass -- if we were to average all of the isotopes based on the weighting of how they exist in nature -- ...
