Question

1-66 indicate whether each of the following statements is true or false. if a statement is false, change it to make it true. (such a rewriting should involve more than merely converting the statement to the negative of itself.)
a. a molecule of an element may be homoatomic or heteroatomic, depending on which element is involved.
b. the limit of chemical subdivision for a compound is a molecule.
c. heteroatomic molecules do not maintain the properties of their constituent elements.
d. only one kind of atom may be present in a homoatomic molecule.

Explanation:

Part a

A molecule of an element has only one type of atom (homoatomic). Heteroatomic molecules have different atoms (compounds). So the statement is false. Rewrite: A molecule of an element is always homoatomic; heteroatomic molecules are of compounds.

A compound’s limit of chemical subdivision that still retains its properties is a molecule. So the statement is true.

Heteroatomic molecules (compounds) have properties different from their constituent elements. So the statement is true (as they do not maintain element properties).

Answer:

False. Rewrite: A molecule of an element is always homoatomic (contains only one type of atom), while heteroatomic molecules are characteristic of compounds (containing different types of atoms).
