A step-by-step explanation of how to draw the MgBr2 Lewis Dot Structure. • For MgBr2 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 Br- ion and add brackets. We put the two ions together to complete the Lewis structure for MgBr2. Note that MgBr2 is also called Magnesium bromide. • ---- 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 MgBr2 we think of it together with other MgBr2 formula units in a crystal (NaCl is a good example of this: https://en.wikipedia.org/wiki/Sodium_.... • Drawing/writing done in InkScape.
