In a ball-and-stick molecular model, what do the sticks represent?

Explanation:

A molecular model that consists of balls in the shape of spheres and sticks is known as a ball-and-stick model.

In this type of model, spherical balls represent the atoms present in the model whereas sticks represents the bonds present between combining atoms.

According to the standard molecular art, different colors of represent specific atoms. For example, black represents carbon atom, white represents hydrogen atom, blue represents nitrogen etc.

Thus, we can conclude that in a ball-and-stick molecular model, sticks represent bonds.
