Write a Lewis structure for each atom or ion. Draw the particle by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons and non-bonding electrons. Show the charge of the atom. Particles: S2-, Mg, Mg+2, P.

The Lewis structure to this question can be described as follows:

Explanation:

Structure of Lewis for  :  

The maximum number of electrons from valence in  is 8 (6 from S as well as 2 from negative change).  

The valence electrons in the Lewis structure are placed on four sides of the atom.  

Thus the structure of Lewis for is as follows:

Lewis Mg Structure:  

Complete valence electrons are 2 in Mg.  

The Lewis structure for Mg, therefore, is as follows:

The Lewis structure for  

The maximum valence of electrons   in is=  0.

Thus, the structure for   is as follows:

Lewis structure for P :

The maximum number of valence electrons in P is = 5.

Thus, the structure for P is=

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

the answer is option a.
