Short explanation

Group 1 elements are known as alkali metals, which include lithium, sodium, potassium, rubidium, cesium, and francium. These elements are characterized by having one electron in their outer shell, which makes them highly reactive. Alkali metals are typically soft and have low melting points compared to other metals. They react vigorously with water to produce hydrogen gas and a corresponding alkali solution. This unique reactivity and physical properties distinguish alkali metals from other groups in the periodic table.

Common mistakes

Misidentifying Group 1 Elements: Remember that Group 1 elements are specifically alkali metals, which have one electron in their outer shell, while transition metals are found in the center of the periodic table and have different properties.
