Understand the Problem
The question encompasses multiple concepts related to chemistry, particularly focusing on the periodic table, the reactivity series of metals, and extraction methods. It asks for key details regarding alkali metals, noble gases, halogens, reactions of metals, and the process of electrolysis, including various equations and reasons for their characteristics.
Answer
Lithium, sodium, potassium. Group 1. Reactivity increases down the group.
The alkali metals are lithium, sodium, and potassium, found in Group 1 of the periodic table. Reactivity increases as you move down the group due to the increase in atomic size and decreased ionization energy. Sodium reacts with water as follows: Na + H2O → NaOH + H2.
Answer for screen readers
The alkali metals are lithium, sodium, and potassium, found in Group 1 of the periodic table. Reactivity increases as you move down the group due to the increase in atomic size and decreased ionization energy. Sodium reacts with water as follows: Na + H2O → NaOH + H2.
More Information
Alkali metals are highly reactive, especially with water, due to a single electron in their outermost shell. They are stored under oil to prevent reactions with moisture in the air.
Tips
Confusing Group 1 (alkali metals) with Group 2 (alkaline earth metals) can lead to mistakes. Remembering common reactions and their products helps in writing correct equations.
