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?

A
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.
B
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.
C
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.
D
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.

Which statement correctly compares an atom of an alkali metal with an atom of the alkaline earth metal next to it on the periodic table?

A
The alkali metal atom forms a +1 ion, while the alkaline earth metal atom forms a +2 ion.
B
The alkali metal atom forms a +2 ion, while the alkaline earth metal atom forms a +1 ion.
C
The alkali metal atom has one less shell of electrons than the atom of the alkaline earth metal.
D
The alkali metal atom has one more shell of electrons than the atom of the alkaline earth metal.
