Question

1. drag and drop the words with the descriptions.

a formula that shows the simplest ratio of atoms in a compound
a formula that shows the actual number of atoms in a compound
a number that represents how many electrons are gained, lost, or shared for an atom to become stable
molecules containing carbon and hydrogen
compound that typically does not contain carbon
a system used to name compounds

Explanation:

1. For "a formula that shows the simplest ratio of atoms in a compound", the correct term is empirical formula as it gives the simplest whole - number ratio of atoms in a compound.
2. For "a formula that shows the actual number of atoms in a compound", molecular formula is the right choice as it represents the actual number of each type of atom in a molecule.
3. For "a number that represents how many electrons are gained, lost, or shared for an atom to become stable", oxidation number fits this description as it indicates the electron transfer (gain, loss, or sharing) for an atom to achieve stability.
4. For "molecules containing carbon and hydrogen", organic molecules are defined as those containing carbon - hydrogen bonds (and often other elements too), so organic is the correct term.
5. For "compound that typically does not contain carbon", inorganic compounds are those that are not organic, i.e., they usually lack carbon - hydrogen bonds, so inorganic is appropriate.
6. For "a system used to name compounds", chemical nomenclature is the system of naming chemical compounds.

Answer:

1. a formula that shows the simplest ratio of atoms in a compound: empirical formula
2. a formula that shows the actual number of atoms in a compound: molecular formula
3. a number that represents how many electrons are gained, lost, or shared for an atom to become stable: oxidation number
4. molecules containing carbon and hydrogen: organic
5. compound that typically does not contain carbon: inorganic
6. a system used to name compounds: chemical nomenclature
