CaCO3 does not have a lewis structure because this molecule is composed of ions. (Ca+2 and CO3-2). you have to draw the lewis structure of the ions separately, as shown in the parenthesis.
Clacium carbonate does not have Lewis structure as whole compound because it is ion compound. Only it's ions have Lewis structure.

This is the chemical formula of calcium nitride.
calcium nitride is ionic.
Calcium nitride is Ca3N2
Calcium phosphate is the chemical name for the molecular compound of the formula Ca3(PO4)2. The Lewis dot structure representing calcium phosphate is:
Nitrogen is in the 3- oxidation state in calcium nitride.
This is the chemical formula of calcium nitride.
something likeCa=N-Ca-N=Ca
calcium nitride is ionic.
Calcium nitride is Ca3N2
Calcium phosphate is the chemical name for the molecular compound of the formula Ca3(PO4)2. The Lewis dot structure representing calcium phosphate is:
Nitrogen is in the 3- oxidation state in calcium nitride.
This method of naming a compound tells you the composition, the formula unit, but not necessarily the structure. As it happens calcium nitride is Ca3N2 is a crystalline near ionic compound. Its red brown in color and hydrolyses readily.
The chemical formula of calcium nitride is Ca3N2.
The Lewis dot for lithium nitride (Li3N) would show 8 electrons (4 pairs) on the N with a -3 charge and no electrons on the 3 Li with each having a +1 charge.
7,68 grams of calcium nitride is equal to 0,052 moles.
