There are a set of rules to remember while distribution off electrons in different orbits. Rule 1 : The maximum number of electrons present in a particular shell is calculated by the formula 2n 2 , where “n” represents the shell number. Now each fluorine atom has six valence electrons to itself. However, the bond consists of two additional valence electrons for each fluorine atom (as the electrons are shared), so both fluorine atoms now have a full octet. Thus fluorine is more stable as a diatomic molecule. Below is a Lewis Structure for elemental fluorine for reference. The Lewis structure shows single bonds, octets on each atom, and a tetrahedral geometry around the Si atom. Some pyrosilicate minerals are akermanite (Ca 2 MgSi 2 O 7 ), lawsonite (CaAl 2 Si 2 O 7 (OH)2 ), and hemimorphite (Zn 4 (OH)2 Si 2 O 7 ).
