CEM 141 Final Exam Questions and Answers Already Passed Why are alpha particles deflected by the nucleus? Because both the alpha particles and the nucleus are positively charged and so the alpha particle is repelled. Is this statement (Dalton's Theory) true or false and why? "All atoms of an element are identical and have the same mass and properties." False. Atoms of the same element can have different numbers of neutrons. What is the evidence that electrons are subatomic pa...

What is a covalent bond? - Answer A covalent bond is a chemical bond that occurs when one or more electron is shared between the atoms. all intermolecular forces are much weaker than covalent bonds. True or False - Answer True. What are three types of intermolecular forces - Answer London dispersion, dipole-dipole, hydrogen bonding What are London dispersion forces? - Answer The intermolecular attractions resulting from the constant motion of electrons. What is a dipole-dipol...

intermolecular forces correct answers forces that hold molecules to other molecules (not bonds within molecules) ion-ion interaction correct answers occurs between ions, with opposite charges attracting and like charges repelling ion-dipole interaction correct answers occur between ions and polar molecules, where the ion is attracted or repelled to a partial charge in the polar molecules (includes interactions between water and dissolved ions) dipole-dipole interaction correct answers o...
