So we're going to have three bonding electrons for carbon and one non bonding. What that basically means is that three electrons that carbon will donate will be part of a bond, while one electron, which will be found here, won't be part of that bond. Now, each h atom will donate one electron each. So let's draw our one electron each. So these two electrons, where one came from h and one came for c, will be shared by these two atoms, and they will create a sigma bond, or also known as a covalent bond. And we can represent that by simply drawing this dashed line here.
