Step-by-step explanation:

Group 1A on the periodic table is more commonly called the alkali metals. These elements include lithium, sodium, potassium, and others, and they all have one valence electron, which makes them highly reactive. They are soft and can be easily cut. Alkali metals are known for forming compounds in the same ratios with similar properties with other elements, which is why they are grouped together in the same column on the periodic table.
