What Makes Metals So Marvelous? - inChemistry

08/10/2019· In metallic bonds, electrons move freely among the atomic nuclei—they are delocalized, so there isn’t a definitive bond in the way molecular and ionic bonds form. When stress is applied, the electrons simply slip over to an adjacent nucleus. Metallic bonding—and the loosely held electrons—is also why metals conduct electricity so well.

Strontium - Wikipedia

Strontium is the chemical element with the syol Sr and atomic nuer 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium. It occurs naturally …
