Alkaline earth metals are a group of six elements in the periodic table that sit directly below the alkali metals. Which means together, they are often abbreviated as Be, Mg, Ca, Sr, Ba, and Ra, covering beryllium, magnesium, calcium, strontium, barium, and radium. Plus, because of their reactivity, relatively low densities, and ability to form stable compounds, these elements have found their way into a surprising number of industrial, medical, and consumer products. So if you have ever wondered what are alkaline earth metals used for, the answer reaches far beyond a simple chemistry textbook. Their uses range from strengthening aircraft frames to brightening fireworks and improving medical imaging.
What Are the Alkaline Earth Metals?
The alkaline earth metals are a family of elements with similar chemical behavior. They are all reactive, but their reactivity increases as you move down the group. Beryllium is relatively stable, while radium is highly radioactive and behaves very differently from its lighter relatives.
The main alkaline earth metals include:
- Beryllium (Be)
- Magnesium (Mg)
- Calcium (Ca)
- Strontium (Sr)
- Barium (Ba)
- Radium (Ra)
Despite the name “alkaline,” these metals do not always form alkaline solutions. The name comes from their oxides, which taste bitter and turn litmus paper blue, similar to an alkali Most people skip this — try not to. Took long enough..
