Which of the following descriptions of the storage requirements for alkali metals is the most accurate? Select the correct answer below: A. They must be kept separate from moisture and oxygen. B. They must be kept separate from other alkali metals. C. They must be kept separate from non-alkali metals. D. They must be kept separate from mineral oil.

A. They must be kept separate from moisture and oxygen

Explanation:

Alkali metals refers to a group of chemical elements in the periodic table. It is the common name given to Group 1 elements (excluding hydrogen). They are generally metallic in nature with physical properties like shining lustre, silvery in appearance etc. Alkali metals include lithium, Pottasium, Sodium, Rubidium etc.

One important chemical property of alkali metals is their high reactivity i.e. they tend to react quickly with other substances. For example, alkali metals react vigorously with water to form hydroxides. They also react with oxygen to form oxides. Due to this highly reactive properties, they are kept or stored away from moisture (water) and oxygen (present in air).
