If a source radiates sound uniformly in all directions and you triple your distance from the sound source, what happens to the sound intensity at your new position?
a. the sound intensity drops to 1 / 27 of its original value. b. the sound intensity increases to three times its original value. c. the sound intensity drops to 1 / 3 of its original value. d. the sound intensity drops to 1 / 9 of its original value. e. the sound intensity does not change.

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.
