Which group of elements is known for having a charge of +1 and includes Lithium, Sodium, and Potassium?

The group of elements known for having a charge of +1 is the Alkali Metals. This classification includes Lithium, Sodium, and Potassium, which are notably the first three elements in Group 1 of the periodic table. These metals have one electron in their outermost shell, and they tend to lose this single electron in chemical reactions, resulting in a +1 charge. This characteristic makes them highly reactive, especially with nonmetals such as halogens.

The Alkaline Earth Metals, found in Group 2 of the periodic table, typically have a charge of +2 due to their two outer electrons. Halogens are found in Group 17 and are known for having a -1 charge when they gain an electron. Noble Gases, located in Group 18, are characterized by their complete valence shell and generally do not form ions under normal conditions. Thus, the Alkali Metals are the distinct group that consistently possesses a +1 charge and includes the elements specified in the question.
