Be certain T or F is clearly indicated. ____ The freezing of H_2O(l) to form ice is endothermic. ____ Adding heat energy to a system always increases the temperature. ____ Every reference elemental form has Delta H degree_f set to zero. ___ Ultraviolet radiation has a longer wavelength than yellow light. ____ Every p subshell has l = 2. ___ No known element has an electron in a g orbital (in the ground state). ____ Unpaired electrons in an atom are only found in partially filled subshells. ____ Elements at the right of the Periodic Table are the most prone to forming cations. _____ Based on configurations, lead would form a 3+ configuration. ____ MRI (Magnetic Resonance Imaging) involves proton magnetic spin in the nuclei of hydrogen atoms.
