Alkaline Earth Metal

Description

An alkaline earth metal refers to any of the chemical elements in Group 2 of the periodic table. These elements are shiny, silvery-white, and have relatively low densities. They are called "alkaline earth metals" as their oxides and hydroxides are alkaline in nature.

Senses and Usages

Sense 1: Chemical Element

As a chemical element, alkaline earth metals are highly reactive, low-density metals with two valence electrons in their outermost energy level. The common alkaline earth metals include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Example Sentences:

• Beryllium is classified as an alkaline earth metal in the periodic table.
• Magnesium is commonly used in the production of lightweight alloys.
• Calcium is an essential nutrient for the development of strong bones and teeth.
• Strontium compounds are utilized in fireworks to produce vivid red colors.
• Barium sulfate is employed as a contrast agent in medical imaging.
• Radium was historically used in luminous paints, but its usage is now regulated due to its radioactivity.

Sense 2: Local Usage

In some regions, particularly in local geology or mining contexts, the term "alkaline earth metal" may be used more broadly to refer to minerals or elements that share similar properties with the traditional alkaline earth metals.

Example Sentences:

• As part of the excavation, the miners discovered a rich deposit of alkaline earth metals.
• The geologist identified various alkaline earth minerals in the rock samples collected from the quarry.
