The alkaline earth elements are metallic elements found in the second group of the periodic table. Can the alkali metals good conducters? They are highly electropositive - meaning they have a tendency to give away their valence electron. B. their large size and high ionisation enthalpy. Some of them will even explode when they come into contact with water. They are mostly not found in free nature as they react quickly and vigorously. More complex, water-insoluble minerals are, however, far more abundant in Earth’s crust. They are all in the first column of the periodic table. Where are alkaline Earth metals found on the periodic table. The Group 1 elements are called the alkali metals. A very dilute gas of atomic sodium (about 1,000 atoms per cubic cm [about 16,000 atoms per cubic inch]) is produced in Earth’s mesosphere (altitude about 90 km [60 miles]) by ablation of meteors. The alkali metals are on the left column of the periodic table highlighted in hot pink. Rechargeable lithium storage batteries that could be suitable for vehicle propulsion or energy storage are the subject of intensive research. All the Group 1 elements are very reactive. These metals have only one electron in their outer shell. They will react rapidly with air and water and the only way to extract them from their compounds is electrolysis, a process not found in nature.

Sodium Chloride, the most common alkali chloride compound, is found in a 3.5% concentration in ocean water and in vast underground deposits (as rock salt) or as flat surface deposits (salt flats). strong base. This process, in which a molten sodium chloride–calcium chloride mixture (to reduce the melting point) is electrolyzed, produces both sodium metal and chlorine. Consider the following statements,
Alkali metals are never found in free state in nature. Group 1 Group 2 Groups 3–12 Group 17. The first 3 alkali metals can be safely stored both under mineral oil or argon. If an element is highly reactive, it's harder to find naturally. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
