HOMEWORK EXAM 1 CHEM 142 QUESTIONS AND ANSWERS GRADED A Is there an attraction between two neutral helium atoms? Explain in detail why or why not. Be sure to include any evidence you have for your claim and how this supports your reasoning. Yes; 2 helium atoms can be attracted because the electrons in the electron cloud are freely moving. This leads to one of the atoms becoming an instantaneous dipole, this will then induce a dipole on the other atom. The opposite partial charges will a...
