[Answer] 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?

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.

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? Tue Aug 06 2002 · An extended periodic table theorises about chemical elements beyond those currently known in the periodic table and proven up through oganesson which completes the seventh period (row) in the periodic table at atomic number (Z) 118.As of 2021 no element with a higher atomic number than oganesson has been successfully synthesized; all elements in the eighth period and beyond … The form of the periodic table is closely related to the electron configuration of the atoms of the elements . For example all the elements of group 2 have an electron configuration of [E] ns 2 (where [E] is an inert gas configuration) and have notable similarities in their chemical properties. In general the periodicity of the periodic table in terms of periodic table blocks is clearly due ... Isotope - Wikipedia Halogen - Wikipedia Sun Mar 11 2001 · The halogens (/ ˈ h æ l ə dʒ ə n ˈ h eɪ- -l oʊ- -ˌ dʒ ɛ n /) are a group in the periodic table consisting of five chemically related elements : fluorine (F) chlorine (Cl) bromine (Br) iodine (I) and astatine (At). The artificially created element 117 tennessine (Ts) may also be a halogen. In the modern IUPAC nomenclature this group is known as group 17.. The name "halogen ... Isotope vs. nuclide. A nuclide is a species of an...
