<h3><u>Answer;</u></h3>

Ionic substances

Single atoms

<h3><u>Explanation;</u></h3>
  • <em><u>The two substances that do not contain molecules with covalent bonds are ionic substances and single atoms.</u></em>
  • <em><u>Ionic substances are those substances that are formed as a result of transfer of electrons from one atom to another, resulting to formation of ions or stable ions. </u></em>Examples of such ions are sodium chloride, potassium iodide, etc. These compounds do not have molecules with covalent bonds.
  • <em><u>Single atoms on the other hand do not have molecules with covalent bond since they exist as an atom and not as a molecule.</u></em> They include elements such as magnesium, sodium,potassium, etc.
