Answer 2

Chemical Bond in Calcium Oxide

The type of chemical bond in calcium oxide (CaO) is an ionic bond. This means that the bond is formed between a metal (calcium) and a non-metal (oxygen), resulting in the transfer of electrons from the metal to the non-metal.

The process of the formation of calcium oxide (CaO) involves the following steps:

1. Formation of Calcium Oxide (CaO): - Calcium oxide is formed through the reaction of calcium metal with oxygen gas. - The balanced chemical equation for the formation of calcium oxide is: ``` 2Ca + O2 → 2CaO ```

- In this reaction, each calcium atom loses two electrons to form Ca2+ ions, and each oxygen atom gains two electrons to form O2- ions. - The resulting calcium ions and oxygen ions then combine to form the ionic compound calcium oxide (CaO).

- This process can be represented as: ``` Ca + O2 → CaO ```

- The ionic bond is formed due to the electrostatic attraction between the positively charged calcium ions and the negatively charged oxygen ions.

- The formation of calcium oxide is an exothermic reaction, releasing a significant amount of heat.

This information is based on the chemical properties of calcium and oxygen, as well as the principles of chemical bonding.
