When you look at a molecule, what do the individual spheres represent?

a. individual atoms

b. a collection of molecules

c. the atoms in water

d. view of water under a microscope.

The correct option is A) individual atoms

Explanation:

In science, the structure of a molecule is often drawn in the form of spheres.  Each sphere shows an individual atom. For example, consider a molecule of H2. It will be drawn as two spheres, each sphere representing a single hydrogen atom. Two spheres will combine to form the H2 molecule. However, the size of the spheres will be equal as the same elements atoms or elements join to form a molecule.
