Question

What is the name of the ionic compound $CaO$ ?

Answer 1

Hint : We know that the ionic compound held together by ionic bonds is classed as ionic compounds. Ionic compounds are neutral compounds made up of positively charged ions called cation and negatively charged ions called anions.

Complete Step By Step Answer:
Here we have,
$CaO$ .
Calcium $Ca$ is a metal and it is the compound’s first name.
Compounds with oxygen $O$ are called oxides. That is the last name ends with ‘ide’.
Since only $CaO$ exists, no further specification is needed.
Hence, the name ionic compound $CaO$ is Calcium oxide. The common name of Calcium oxide is Quicklime.

Note :
Due to the presence of the strong force of attraction between the positive and negative ions, ionic compounds are solids and are hard to break. They generally break into pieces when pressure is applied, hence they are considered brittle. Also ionic compounds have high melting and boiling points. Ionic compounds do not conduct electricity in solid state but are good conductors in a molten state.
