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. [2]

2024年10月30日 · 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.
Group 2 Elements: The Alkaline Earth Metals - Chemistry …
2023年6月30日 · The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals. Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the Group 1 ...
20.5: The Alkaline Earth Metals (Group 2) - Chemistry LibreTexts
Alkaline earth metals dissolve in liquid ammonia to give solutions that contain two solvated electrons per metal atom. The alkaline earth metals have a greater tendency than the alkali metals to form complexes with crown ethers, cryptands, and other Lewis bases.
Trends of the Properties of Group 2 (Alkaline Earth) Metals
2022年7月20日 · Alkaline Earth Metals include Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). Metals become more reactive as they move down the group. As two electrons are lost from their valence shells, all Group 2 metals form 2+ ions. The top metal cations in the group are smaller in size than those at the bottom.
Alkaline Earth Metals: Group 2 Elements, Properties & Compounds
2023年8月25日 · Alkaline Earth Metals are a set of six chemical elements in the periodic table’s group 2. Beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra) are the elements involved (Ra). Alkaline Earth Metals are s-block elements as the last electron enter into the s-subshell.
Trends in Group 2: The Alkaline Earth Metals - Save My Exams
2024年10月27日 · Group 2: Trends Chemical trends. All elements in Group 2 (also called alkali earth metals) have two electrons in their outermost principal quantum shell. All Group 2 metals can form ionic compounds in which they donate these two outermost electrons (so they act as reducing agents) to become an ion with +2 charge (so they themselves become oxidised)
