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?\nthe 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.\nthe 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.\nthe 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.\nthe 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:

In a group of the periodic table, as you go down the group, atomic size increases. Larger atoms have valence - electrons farther from the nucleus. These valence - electrons are more easily removed (lower ionization energy). Metals react by losing electrons. So, metals at the bottom of a group are more reactive as their valence - electrons are easier to remove.

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.
