Analyze the difference between Ionic compounds and covalent compounds and their structure and chemical outputs. What is the main difference between a covalent bond and an Ionic bond?



  1. Covalent bonds occur because of sharing electrons between atoms

  2. Ionic bonds occur due to the distribution of electrons

  3. Ionic and Covalent bonds are very much the same

  4. Covalent bonds happen when electrons are transferred

Covalent bonds happen when electrons are transferred

Adjusting for the octet rule, does the sharing of valence electrons satisfy this rule during a covalent bond? and how would it work for Cl2 



  1. Yes, because when the valence electrons are shared, they give both the atoms a full shell of 8 valence electrons at the same time

  2. Yes, because 2 electrons are circling around both the elements and are sharing the 2 valence electrons 

  3. No, because neither element has a full shell of valence electrons at any time 

  4. None of the above

  • Yes, because 2 electrons are circling around both the elements and are sharing the 2 valence electrons
