Hi! This is a homework question that I'm supposed to answer but that I really do not understand. "Identify two repulsive forces and two attractive forces that influences the formation of chemical bonds between two atoms." I noticed that this question was already posted once at this website but I was not able to understand where the question went, so I'm posting it again. I'm not sure if I'm just reading too much into the question or what but I read the question and I don't even know where to start. I tried looking up attractive and repulsive forces on the Internet but couldn't find any good sources. (I'm doing this through an independent learning centre, so I can't ask a teacher.) I do not recall reading any information on this subject in the last lesson,. First, what are the two repulsive forces and two attractive forces that the question is asking about? How do van der Waals forces (they are attractive right?) and dipole-dipole forces, etc. fit in with this question? I'd really appreciate any help. Thanks!
