atoms of elements at the top of a group on the periodic table are smaller than the atoms of elements at the bottom of the group. how does this help explain the difference in the reactivity of metals within a group? the valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the top are more reactive than those at the bottom. the valence electrons of the larger atoms are farther from the nucleus and are harder to remove, so the metals near the bottom are more reactive than those at the top. the valence electrons of the larger atoms are farther from the nucleus and are harder to remove, so the metals near the top are more reactive than those at the bottom. the valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the bottom are more reactive than those at the top.

Answer

Brief Explanations:

Metals react by losing valence - electrons. In a group, as we go down, atomic size increases. Larger atoms have valence electrons farther from the nucleus. These electrons experience less nuclear attraction and are easier to remove. So, metals at the bottom of a group are more reactive as they can lose electrons more readily.

Answer:

The valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the bottom are more reactive than those at the top.
