Verified step by step guidance

Identify the typical charge of group 1 metals: Group 1 metals (alkali metals) have a +1 charge because they lose one electron to achieve a stable electron configuration.

Understand the nature of ionic compounds: Ionic compounds form when metals transfer electrons to nonmetals, resulting in positively charged metal ions and negatively charged nonmetal ions that combine in ratios to balance the total charge.

Examine the charges of the nonmetal groups: Group 17 (halogens) typically gain one electron to form ions with a -1 charge, Group 16 (chalcogens) form ions with a -2 charge, Group 15 (pnictogens) form ions with a -3 charge, and Group 18 (noble gases) are generally inert and do not form ions.

Determine which group forms a one-to-one ratio with group 1 metals: Since group 1 metals have a +1 charge and group 17 nonmetals have a -1 charge, they combine in a 1:1 ratio to form neutral ionic compounds.

Conclude that group 17 (halogens) react with group 1 metals to form ionic compounds in a one-to-one ratio because their charges balance perfectly without needing multiple atoms of either element.
