one red ball
two white balls
three sticks
What do the sticks represent?

The sticks in the ball-and-stick model of formaldehyde represent covalent bonds between the atoms in the molecule.

The sticks in the ball-and-stick model of formaldehyde represent the chemical bonds between the atoms.

The sticks in a ball-and-stick model of a molecule represent the chemical bonds between atoms. Each stick corresponds to a single bond between atoms. In the case of formaldehyde (CH2O), there are three sticks representing the three chemical bonds in the molecule.
