(b) Why are ionic compounds usually hard ?​

Answer 1

Answer:

i dont know

Explanation:

Answer 2

Answer:

A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes. Hydrocarbons are compounds that contain only hydrogen and carbon.

1. For the formation of Na2O: It is an ionic compound and sodium has 11 atomic number and oxygen has 8 atomic number. . Therefore two atom of sodium will combine with one atom of oxygen and each sodium will lose one electron to oxygen and therefore completing its octet.
2. The ionic compounds are usually hard because the ions are held by strong electrostatic force of attraction as the positive and negative ions are strongly attracted to each other and difficult to separate them apart.
