A
Group 1 (alkali metals)
B
Group 2 (alkaline earth metals)
C
Group 18 (noble gases)
D
Group 17 (other halogens)
검증된 단계별 안내1
Recall that halogens are elements found in Group 17 of the periodic table and are highly reactive nonmetals.
Understand that halogens tend to gain one electron to achieve a stable noble gas electron configuration, forming anions with a charge of -1.
Identify which groups of elements tend to lose electrons to form cations, making them likely to react with halogens. Group 1 elements (alkali metals) lose one electron to form +1 cations.
Recognize that the electrostatic attraction between the +1 cations of Group 1 metals and the -1 anions of halogens leads to the formation of ionic compounds.
Conclude that halogens most readily form compounds with Group 1 elements because of their complementary electron transfer tendencies.
