HOMEWORK EXAM 1 CHEM 142 2025 Questions and Answers 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. - --CORRECT ANSWER--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 attract one another. The force of attraction is called LDFs explain two helium atoms as they approach one another, and explain what is happening. - --CORRECT ANSWER--In phase one, the two atoms exist with fluctuating electron clouds. In phase two, one He atom forms an instantaneous dipole when at any given time the electrons exist near one side of the atom. In phase three, the instantaneous dipole induces the other He into forming another dipole and the partial charges attract each other ....COPYRIGHT ©️ 2025 ALL RIGHTS RESERVED...TRUSTED & VERIFIED 1
