A step-by-step explanation of how to draw the Na3P Lewis Dot Structure. • For Na3P 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 P 3- ion and add brackets. We put the two ions together to complete the Lewis structure for Na3P. Note that Na3P is also called Sodium phosphide. • For a complete tutorial on drawing Lewis Structures, see my video: • How to Draw Lewis Structures: Five Ea... • For more practice, see • Lewis Dot Structure Practice Problems... • To learn to find the valence electrons: • Finding the Number of Valence Electro... • 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 Na3P we think of it together with other Na3P formula units in a crystal (NaCl is a good example of this: https://en.wikipedia.org/wiki/Sodium_.... • Get more chemistry help at http://www.thegeoexchange.org/chemist... • Drawing/writing done in InkScape.
