Question

Define ionic bond. Explain the formation of CaO.​

Answer 1

Answer:

1) Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds. It is one of the main types of bonding along with covalent bonding and metallic bonding. Ions are atoms with an electrostatic charge.

2) Calcium reacts with oxygen to form an ionic compound calcium oxide (CaO). The atomic number of calcium is 20 and that of oxygen is 8 . By losing two electrons ,the calcium atom forms a calcium ion( Ca2+ ) ,and by gaining two electrons ,the oxygen atom forms an oxide ion (O2-). ... Thus calcium oxide contains ionic bonds .
