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 above
because it conducts electricity due to reason it compound is ionic compound in ionic compound conduct electricity in molten state of solution state due to ionization
