    We have the shells K,L,M,N. Are the number of shells just 4 or more than 4? If more than 4, what do we call them?

    Although magnesium chloride doesn't have any chlorine molecule, why is its formula MgCl2 and not MG2Cl?

      Because there are 2 molecules of chlorine not magnesium and magnesium has valency of 2 and that of chlorine is 1.So,1 magnesium molecule needs 2 chlorine molecules to get an inert gas configuration

    As all Ionic compounds are polar they form salts.
    Salts(ionic compounds) are generally crystalline in nature and hence contain water of crystallization.

    Why do ionic compounds form crystals when a specific amt. of water is added and not in their anhydrous form?

    what are the maximum capacity of m shell and n shell?

    why are octets stable and not reactive?

    are there more shells like o shells, p shells?

      The maximum capacity of the M shell is 18 and that of the N shell is 32.
      Octets are stable because that's when the maximum capacity of the orbit is reached, i.e., there can't be more than 8 electrons in that orbit, so the atom becomes stable as it has reached its capacity.
      There is an o shell, but I'm not too sure about a p shell
