Answer
Group 1 metals have a single electron in their outermost electron shell. This configuration results in similar chemical properties, such as high reactivity and the ability to easily lose that one electron, leading to the formation of +1 ions. The consistent pattern of having one valence electron is the reason these metals are classified in group 1.
Step 2
