Carbon has 4 electrons in its valence shell, thus making 4 covalent bonds.
<h3>How is the Lewis structure?</h3>
The Lewis structure shows the formation of bonds in a molecule, as well as the atoms involved and the valence electrons of each of them. Atoms form chemical bonds with each other in order to achieve electronic stability.
With this information, we can conclude that Carbon has 4 electrons in its valence shell, thus making 4 covalent bonds.
