Module 7-Naming and Formulas Quiz

Using the ionic compounds table shown, which element is always written first in an ionic compound: the metal element or the nonmetal element?

• the metal element

• the nonmetal element

Using the same table, compare the names of metal elements by themselves to their names when part of a compound. Do the names of metal elements change when they are written in compound names?

• No, metal element names stay the same.

• Yes, they change to end with -ide.

• Yes, they use prefixes such as mono-, di-, tri-.

• Yes, they use Latin-derived names only in compounds.

Using the same table, compare the names of nonmetal elements by themselves to their names when part of a compound. Do the names of nonmetal elements change when they are written in compound names? If yes, how do they change?

• No, nonmetal names stay the same.

• Yes, they change to end with -ide.

• Yes, they are written with Roman numerals.

• Yes, they begin with hydro-.

Look at the table of covalent compounds. Compare the names of the first nonmetal elements by themselves to their names when they are part of a compound. Do the ends of the first nonmetal element names change when they are written in compound names?

• They remain the same (no ending change).

• They change to the -ide ending.

• They change to the -ate ending.

• They change to the -ite ending.
