Question

explain the formation of cao with electron dot structure ?​

Answer 1

CaO.
calcium oxide..
i hope you can understand

Answer 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-).The calcium ion has 2 units positive charge whereas the oxide ion has 2 units negative charge ,which are held together by strong electrostatic force of attraction to form calcium oxide compound Ca2+O2- .Thus calcium oxide contains ionic bonds .The electron dot representation for the formation of calcium oxide is shown below ,
