    Covalent bonding is the sharing of electrons. Ionic bonding is when one element loses one electron and the other element gains an electron. After this they have a stable outer shell and become ions.

    They'll tell you in the exam, it's usually outer shell

    If the question allows you to only draw the outer shell then yes. Otherwise, assume that you're not allowed and draw all of them

    Yes, outer shells only !!

    If AQA, ensure you can do the following simple molecules; water, ammonia, hydrogen, hydrogen chloride, methaneand oxygen,

    Yes, because the inner shells are stable and filled to their maximum number of electrons. For example, if you are asked to draw an element that has three shells, you draw the third shell as the first and second are filled with two electrons and eight electrons respectively, which makes them stable as they follow the duet and the octet rules.

    This may confuse people, but I understand what you are saying. I slightly adjusted your comment which may make it clearer for others. Good luck !

    When drawing covalent bonding, you need to make sure atoms are shared between the pairs. Ionic bonding is the complete transfer of electron(s) between atoms and is a type of chemical bond that generates two oppositely charged ions. The question itself will mention specifically whether or not you should draw it with all shells or outer shell only. Usually, they ask for the outer shell only. You can use the periodic table to help you by looking at the group the element(s) is in.

    Ensure you are clear with ionic and covalent bonding. Your first sentence is not clear that you understand.
