Naming Simple Ionic Compounds

Which of the following combinations would need roman numerals in the name?

• potassium + fluorine

• beryllium + oxygen

• boron + iodine

• silver + oxygen

What is the correct name for Ca(ClO)2?

• Calcium hypochlorite

• Calcium chloride

• Calcium perchlorate

• Calcium dichloride

Answer explanation

Ca(ClO)2 is named calcium hypochlorite because it contains calcium (Ca) and hypochlorite ions (ClO). The other options refer to different compounds, making calcium hypochlorite the correct name.

Prefixes such as 'di-' and 'tri-' are used in naming ionic compounds.

Answer explanation

Prefixes like 'di-' and 'tri-' indicate the number of atoms in molecular compounds, not ionic compounds. Ionic compounds are named based on the charges of the ions involved, so the statement is incorrect.

Write the chemical formula for each of the following binary ionic compounds: Aluminum chloride, Magnesium chloride, Potassium nitride, Lithium sulfide, Barium bromide.

Answer explanation

The chemical formulas for the compounds are: Aluminum chloride (AlCl3), Magnesium chloride (MgCl2), Potassium nitride (K3N), Lithium sulfide (Li2S), and Barium bromide (BaBr2). Each formula reflects the charges of the ions.
