Question 2
Friends on a crowded ice skating rink tend to stay together. Strangers, however, tend to disperse. Is this behavior typical of atoms forming chemical bonds or molecules interacting? Explain.
A) No, atoms forming chemical bonds are just the opposite. Chemical bonds forming or molecules reacting would be more analogous to strangers tending to stay together and friends dispersing.
B) Yes, atoms forming chemical bonds are analogous to friends in the rink. Atoms held together by covalent bonds represent a molecule.
C) No, opposites (like strangers) attract to form stable covalent bonds in the world of atoms and molecules.
D) Yes and No; No, because this behavior is not typical of atoms forming chemical bonds, but yes since it is typical of molecules interacting.
