on, hydrogen and oxygen have fuller
outer shells after bonding and contain hydrogen – 2, ca
on – 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
ca
on atom have in its outer shell? _______ Remember that in covalent bonds, electrons are
shared so that each element has a full outer shell.
