Now, molecular models represent a way to describe the chemical bonds between elements through the use of color coded balls for elements. So here we have these color coded balls that are also kind of arranged in terms of size. Don't worry about the differences in size. What it's important remember the different types of colors associated with elements on the periodic table. So if we have a white ball here that represents hydrogen, a black ball represents carbon, then we have here the sky blue ball, which is nitrogen. Next we have this red ball here, which is oxygen. Then here we're going to have this grayish off white one, which is flooring. This Navy Blue one is phosphorus, lime green, is sulfur, and then finally this I guess forest green looking one is chlorine. So these are the different color codes for these spheres that represent different elements on the periodic table. No.

Here we need to determine the structural formula for the following compound, given as a molecular model. Remember your white balls there represent hydrogen, and then these two black ones represent carbon. So this structure in it has two carbons and six hydrogen. This translates to a formula of C2, age six. So here this would represent the structural formula of the molecular model that's given to us within this example question.
