A step-by-step explanation of how to draw the NH4HCO3 Lewis Dot Structure.
For NH4HCO3 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: [ Ссылка ]).
Next, we'll draw the Lewis Structure for the CO2 2- ion and add brackets. We put the two ions together to complete the Lewis structure for NH4HCO3. Note that NH4HCO3 is also called Ammonium bicarbonate.

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 NH4HCO3 we think of it together with other NH4HCO3 formula units in a crystal (NaCl is a good example of this: [ Ссылка ]).
Lewis Structures are important to learn because they help us understand how atoms and electrons are arranged in a molecule or compound, such as Ammonium bicarbonate.
