Guida verificata passo dopo passo1
Understand that the periodic table is organized into groups (columns) and periods (rows), where elements in the same group share similar chemical properties.
Recall that alkali metals are highly reactive metals known for having a single electron in their outermost shell, which they readily lose to form +1 ions.
Identify that the group containing alkali metals is Group 1, which includes elements like lithium (Li), sodium (Na), and potassium (K).
Note that Group 18 contains noble gases, which are inert; Group 2 contains alkaline earth metals; and Group 17 contains halogens, which are nonmetals.
Therefore, the group number known as the alkali metals is Group 1.
