Explanation:
Using the periodic table, to predict the chloride that is ionic or not, we should first understand how ionic compounds are formed.
Ionic compounds are formed between a highly electronegative element and less electronegative one.
- It is usually a bond formed between metals and non-metals.
- Metals are on the left block and non-metals on the right block.
- In the formation of this bond type, a metal loses its excess electrons and becomes positively charged.
- A non-metal gains the electron and becomes negatively charged.
- The electrostatic force of attraction between the two species causes the formation of ionic bonds.
- Ionic bonds forms between metals and non-metals with appreciable electronegative differences.
