Classify the following as atoms or molecules. Drag the appropriate items to their respective bins. a. Mg S b. H2 SO3 c. HBr

a) Mg and S = atoms

b) H2 SO3 = molecules

c) HBr = molecule

Explanation:

Step 1: Data given

Atoms = An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. We can find them on the periodic table.

Molecules = A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

a. Mg S = Magnesium and sulfur both are atoms, we both can find them on the periodic table

b. H2 SO3 = H2 is a molecule that contains 2 hydrogen atoms

SO3 is a molecule that contains 1 sulfur atoms and 3 oxygen atoms

c. HBr = HBr is a molecule that contains 1 hydrogen and 1 bromine atom
