Strontium (Sr)

Strontium (Sr) is a soft, silvery metallic element found naturally in the Earth's crust, often near calcium and other alkaline earth metals. It shares similar properties with calcium and can replace it in biological processes, which is why it can affect bones. Strontium occurs in mineral deposits and is used in various applications, including fireworks, ceramics, and medicine—particularly in treatments for osteoporosis, where it helps strengthen bones. Although similar to calcium, excessive exposure can be harmful. Its ability to mimic calcium in the body and its vibrant use in industries make it an interesting and useful element.
