How to Draw the Lewis Dot Structure for KHCO3: Potassium bicarbonate

A step-by-step explanation of how to draw the KHCO3 Lewis Dot Structure. For KHCO3 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 on t...  ). Next, we'll draw the Lewis Structure for the HCO3- ion and add brackets. We put the two ions together to complete the Lewis structure for KHCO3. Note that KHCO3 is also called Potassium bicarbonate. For a complete tutorial on drawing Lewis Structures, see my video:    • How to Draw Lewis Structures: Five Easy Steps   For more practice, see    • Lewis Dot Structure Practice Problems (wit...   To learn to find the valence electrons:    • Finding the Number of Valence Electrons fo...   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 KHCO3 we think of it together with other KHCO3 formula units in a crystal (NaCl is a good example of this: https://en.wikipedia.org/wiki/Sodium_....
