Answer:
The Lewis structure to this question can be described as follows:
Explanation:
Structure of Lewis for  [tex]S^{2-}[/tex]: Â
The maximum number of electrons from valence in [tex]S^{2-}[/tex] Â is 8 (6 from S as well as 2 from negative change). Â
The valence electrons in the Lewis structure are placed on four sides of the atom. Â
Thus the structure of Lewis for [tex]S^{2-}[/tex] is as follows:
[tex]\left[\begin{array}{ccc} &. .&\\: &S&:\\&. .&\end{array}\right] ^{2-}[/tex]
Lewis Mg Structure: Â
Complete valence electrons are 2 in Mg. Â
The Lewis structure for Mg, therefore, is as follows:
[tex]\ . \\ Mg\\ \ .[/tex]
The Lewis structure for  [tex]Mg^{2+}[/tex]
The maximum valence of electrons  [tex]Mg^{2+}[/tex] in is=  0.
Thus, the structure for  [tex]Mg^{2+}[/tex] is as follows:
 [tex]Mg^{2+}[/tex]
Lewis structure for P :
The maximum number of valence electrons in P is = 5.
Thus, the structure for P is=
