A step-by-step explanation of how to draw the Na2CO3 Lewis Dot Structure. • For Na2CO3 we have an ionic compound and we need to take that into account when we draw the Lewis Structure. We’ll first draw the metal and put it in brackets with its charge on the outside (video: finding ionic charge: • Finding the Ionic Charge for Elements... ). • Next, we'll draw the Lewis Structure for the CO3 2- ion and add brackets. We put the two ions together to complete the Lewis structure for Na2CO3. Note that Na2CO3 is also called Sodium carbonate. • Explanation of the Lewis Structure for CO3 2- • • CO32- Lewis Structure - How to Draw t... • ---- Lewis Resources ---- • • Lewis Structures for Ionic Compounds: • How to Draw Lewis Dot Structures for ... • • Lewis Structures for Covalent Compounds: • How to Draw Lewis Structures: Five Ea... • • Counting Valence Electrons: • Finding the Number of Valence Electro... • • Calculating Formal Charge: • Formal Charges: Calculating Formal Ch... • • Exceptions to the Octet Rule: • Exceptions to the Octet Rule • More chemistry help at https://www.Breslyn.org. • Note that is it more common to draw Lewis Structures for covalent (molecular) compounds where valance electrons are shared. In the case of ionic compounds, where we have a metal bonded to a non-metal (or group of non-metals), the Lewis diagram represents a formula unit. Many of these formula units make up a crystal lattice. So when we talk about the structure for Na2CO3 we think of it together with other Na2CO3 formula units in a crystal (NaCl is a good example of this: https://en.wikipedia.org/wiki/Sodium_.... • Drawing/writing done in InkScape.
