Aparticle (m = 50 g, q = 5.0 mc) is released from rest when it is 50 cm from a second particle (q = -20 mc). determine the magnitude of the initial acceleration of the 50-g particle.

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.
