Carry out the experiment the way you described it in task 1, part D. Perform three trials for each drop height, and record the data in the table. Estimate heights to the nearest centimeter. (You may choose to reduce the simulation rate and watch the bounces in slow motion to improve your data collection.) Finally, average the bounce height measurements to get a final reading. Round the average bounce heights to the nearest whole number.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
