Alkaline-earth metal | Properties, List, & Reactivity | Britannica
Alkaline-earth metal, any of the six chemical elements that comprise Group 2 of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The alkaline-earth elements are highly metallic and are good conductors of electricity.

Alkaline earth metal – Wikipedia
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). [1] The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. []

30 juin 2023Calcium is the 20th element in the periodic table. It is a group 2 metal, also known as an alkaline-earth metal, and no populated d-orbital electrons. Calcium is the fifth most abundant element by mass (3.4%) in both the Earth’s crust and in seawater. All living organisms (in fact, even dead ones) have and need calcium for survival.

Group 2 Periodic Table | Elements & General Properties
Group 2 elements are called alkaline metals because they form alkaline solutions, hydroxides, when reacting with water and their oxides are found in the earth’s crust. ALKALINE METALS They have low electron affinity. Group 1 metals are less reactive than group 2 metals. Its valence shell contains 2 electrons They have low electronegativity

Group (periodic table) – Wikipedia
In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

Periodic table – Wikipedia
Chemistry Portal. v. t. e. The periodic table, also known as the periodic table of the elements, arranges the chemical elements into rows (periods) and columns (groups). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which says that when the arranged in order …

The naturally abundant isotopes of the alkaline earth elements are listed in Table 4.1.4 .4. All of the 25 isotopes of radium are radioactive, and while radium-223, radium-224, and radium-228 are found in nature as decay products of either uranium or thorium, they are only present in trace amounts.
