3. Which four elements make up the bulk of all living things?
Answer: The bulk of all living things contain carbon (C), Nitrogen (N), hydrogen (H) and
oxygen (O).
Answer: Full outer shell of hydrogen contains 2 electrons.
5. A FULL outer shell of Carbon has how many electrons?
Answer: Carbon contains 2 shells. The first shell contains 2 electrons and 2
nd
shell contains 4
electrons. The full outer shell of carbon contains 4 electrons.
1. How does the lecture define elements?
Answer: Elements are the basic substances that everything on Earth is made of from Apples to, rock to,
and telephones to Zebras.
2. Which of the following are made of elements?
a) A computer keyboard
b) You
c) A wooden chair
d) The glass in a window
Answer: All of them are made up of elements.

6. A FULL outer shell of Oxygen has how many electrons?
Answer: Oxygen also contains 2 shells. The first shell contains 2 electrons and 2
nd
shell contains
6 electrons. The full outer shell of oxygen contains 6 electrons.
7. Did the atoms that make up ethyl alcohol have full outer shells before bonding?
Answer: No. The atoms making up ethyl alcohol do not have full outer shells before bonding.
8. Did the atoms that make up ethyl alcohol have full outer shells after bonding to form ethyl alcohol?
Answer: Yes. The atoms making up ethyl alcohol are carbon, hydrogen and oxygen have fuller
outer shells after bonding and contain hydrogen – 2, carbon – 8 and oxygen – 8 electrons in the
outer shell.
9. Explain where the energy is in ethyl alcohol below?
Answer: Energy occurs in the bonds formed between these atoms by sharing the electrons.
10. In that same ethyl alcohol (shown below in a different way), how many electrons does one
carbon atom have in its outer shell? _______ Remember that in covalent bonds, electrons are
shared so that each element has a full outer shell.
Answer: Carbon generally contains 2 shells. First shell contains 2 electrons and 2
