A waterfall includes a section where the water drops through a vertical
distance of 622 m. If the water crests the top of the falls with negligible
speed, how fast would it be traveling at the bottom if air resistance and
other frictional forces were negligible?

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
