The term "alkaline-earth" refers to a group of metallic elements in Group 2 of the periodic table, which includes beryllium, magnesium, calcium, strontium, barium, and radium. These elements are characterized by their reactive nature, especially with water, and can form alkaline hydroxides.
The term "alkaline-earth" is commonly used in scientific contexts, particularly in chemistry and materials science. It appears more frequently in written form than in oral speech, given its technical nature.
Лужноземельные металлы необходимы в различных промышленных процессах.
In the reaction of alkaline-earth metals with water, hydrogen gas is produced.
При реакции лужноземельных металлов с водой выделяется водород.
Barium is one of the most well-known alkaline-earth elements used in medical imaging.
While "alkaline-earth" itself is not commonly found in idiomatic expressions, elements and compounds from the alkaline-earth metals can form parts of scientific idioms or phrases, particularly in chemistry. Below are a few related idiomatic expressions that incorporate chemical concepts:
