  1. 1.

    In an orbital research station, an automated synthesis unit analyzes two unknown samples: Sample Alpha belongs to Period 3, Group 2, while Sample Beta belongs to Period 3, Group 17 of the periodic table. Based on the fundamental organization of periods and groups, which statement correctly compares these two elements?

    • A) Both elements exhibit nearly identical chemical reactivity because elements sharing the same period belong to the same chemical family.
    • B) Sample Alpha has fewer occupied electron shells than Sample Beta because it sits in a lower-numbered column of the periodic table.
    • C) Both elements possess the same number of occupied electron shells, but Sample Beta possesses more valence electrons than Sample Alpha.
    • D) Sample Alpha possesses more valence electrons than Sample Beta because periods determine the number of outermost electrons.
