Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table.B
Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.C
Element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons.D
Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
