When using the “ball and stick” drawing method of drawing a compound, which element usually goes in the center of the model?

Answer 1

In the "ball and stick" model of a compound, the element that usually goes in the center is typically the element that can form the most bonds or has the highest valency. In many cases, this is carbon, especially in organic compounds. Carbon can make four bonds, allowing it to serve as a central hub for connecting other elements, such as hydrogen, oxygen, nitrogen, and others, which are represented as balls attached to the sticks (bonds). In compounds where carbon is not present, other central atoms might include oxygen or nitrogen, depending on the connectivity and structure of the specific molecule.
