question 38

Multiple Choice

Refer to the figure below. An oxygen atom by itself is very reactive, whereas an oxygen atom that has combined with two hydrogen atoms to form a water molecule is very stable.What explains this observation?

• A) Oxygen starts out with a total of eight electrons and becomes more stable when it adds more electrons.
• B) The eight protons in the oxygen nucleus need additional electrons from hydrogen atoms to help neutralize their charge.
• C) The two electrons in the innermost shell of an oxygen atom need two additional electrons to balance out.
• D) The mass provided by the two hydrogen atoms adds to the mass of the oxygen atom, which increases the stability of the entire structure.
• E) An oxygen atom only has six electrons in its valence shell and needs two electrons from hydrogen to fill this shell.
