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.

N1 a golfer wants to hit a ball with the maximum range (the horizontal distance travelled by the ball before it hits the ground) possible. she has four available clubs (a, b, c, d), each of them will give the ball a different initial angle to the horizontal. assuming that the initial speed of the ball will be the same for all of the clubs, which one of the clubs should she choose? assume that alr resistance is negligible. club a: initial angle to the horizontal 10 degrees. club b: initial angle to the horizontal 25 degrees. club c: initial angle to the horizontal 40 degrees. club d: initial angle to the horizontal 55 degrees.
