Answer :
Final answer:
The Lewis symbols for Carbon, Nitrogen with a -3 charge, Potassium with a +1 charge, and Sulfur are depicted as C::, N::::: (-3), (+), and ::S:: respectively. These symbols represent the valence electrons in each atom or ion.
Explanation:
The Lewis symbols for each atom or ion are:
a. Carbon (C) : C ::
b. Nitrogen with -3 charge (N3-) : N :::: :
c. Potassium with +1 charge (K+) : +
d. Sulfur (S) : : :S:::
Lewis symbols are atomic symbols surrounded by dot pairs or Lewis dots which represent the valence electrons of the atom. The number of dots equals the number of valence electrons in the atom. For ions, the charge is indicated as a superscript.
