Structural Model

Let's start with the structural model of methane. The atoms are colored using CPK colors. Here are some common elements and their CPK color:

HydrogenWhite
CarbonGray
NitrogenBlue
OxygenRed
PhosphorousOrange

 

First, we see the model, a representation of lines connecting the center of each covalently-bonded atom.

A model represents bonds as lines and atoms as spheres, very similar to physical models that you may have used in organic chemistry, which give an impression of structure.
