Question

explain the formation of calcium oxide with dot structure

Answer 1

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-).
