About :

Born of electricity. The elements that we will talk about today were discovered or first obtained in pure form by electrolysis. They are all metals. In compounds, they almost always exhibit a valence of two, and are located in the second group of the periodic table. These are beryllium, magnesium, calcium, strontium, barium and radium. When dissolved in water, most of these elements form alkalis... And since the ancient alchemists called oxides by the word "earth", these elements are historically called alkaline earth elements. Let's consider their chemical properties. In this issue: What kind of fire is not afraid of water, sand and carbon dioxide? What did the first flashbulb look like? How to clean a kettle from scale? What substances do fireworks consist of? #chemistry #experiments #experiments #fireworks #chemicalexperiments
