Question

a) Explain the formation of Sodium oxide and Calcium chloride by the transfer of electrons.
b) What are the ions present in these compounds?
c) Why do ionic compounds not conduct electricity in solid state but conduct electricity in molten and
aqueous state?​

Answer 1

Answer:

here is your answer hope it helps ☺️

Explanation:

a= Calcium reacts by lose of 2 electrons. Chlorine reacts by gaining one electron. Since we have two electrons to be lost by Calcium, we will have two atoms of Chlorine to combine with the two electrons

b=The ions present in Na2O are sodium ions 2Na+ and oxide ion O2-. The ions present in MgO are magnesium ion Mg2+ and oxide ion O2-. (i) Write the electron-dot structures for sodium, oxygen and magnesium. (ii) Show the formation of Na2O and MgO by the transfer of electrons.

c= Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
