Naming Chemical Compounds Quiz

The metal is named first and then the non-metal with the ending -ide. For example, NaCl is sodium chloride because Na is sodium (metal) and Cl is chlorine (non-metal with -ide as the suffix).

• ionic bond

• nonmetal bond

The positively charged particle is named first and the elements are given prefixes to show how many atoms are present. The second element is given the suffix -ide. The first element does not get a prefix if it only has 1 atom. For example, CO₂ is named carbon dioxide. N₂O₅ is dinitrogen pentoxide.

• ionic bond

• nonmetal bond

These types of substances usually have hydroxide (OH) in them, so they are named in the same way an ionic bond is named. The first element name is stated followed by hydroxide. For example, NaOH is sodium (Na) hydroxide (OH).

• bases

• acid

These types of substances are named for the hydrogen atom(s) and for the ion. Hydrogen is represented by the prefix hydro-. The first syllable of the ion is attached. Finally, -ic is added as a suffix to the word. For example, hydrochloric where Hydro- for hydrogen (H), chlor is the first syllable of chlorine (Cl), and -ic is the suffix.

• bases

• acid
