Runner a is initially 5.3 km west of a flagpoleand is running with a constant velocity of8.8 km/h due east. runner b is initially 4.8km east of the flagpole and is running with aconstant velocity of 7.9 km/h due west. how far are the runners from the flagpolewhen their paths cross

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.
