What is the element name Sr?
Strontium is a soft, silver-yellow, alkaline-earth metal. It has three allotropic crystalline forms and in its physical and chemical properties it is similar to calcium and barium. Strontium reacts vigorously with water and quickly tarnishes in air, so it must be stored out of contact with air and water.
Is SR a metal or nonmetal?
Strontium is a soft metal like lead and, when freshly cut, has a silvery lustre. It rapidly reacts in air to take on a yellowish colour; therefore, it must be protected from oxygen for storage.
What is Sr in human body?
Strontium (Sr) is a metal that is closely related to calcium (Ca) in the body, and has beneficial or toxic effects on bone formation. Ninety-nine percent of strontium is stored in the teeth and bones after uptake in the body.

What element is bl?
Belarium is the hypothetical chemical element with the symbol Bl and atomic number 210. It has to be synthetically made and it’s not found in nature. It is named after the European country Belarus which is in Eastern Europe. Nearly all of Belarium’s isotopes are unstable.
Where is strontium found in the human body?
Strontium is a silvery metal found naturally as a non-radioactive element. About 99% of the strontium in the human body is concentrated in the bones. Several different forms of strontium are used as medicine.
Can you take calcium and strontium together?
Three good reasons not to take strontium Strontium has a chemical similarity to calcium and will replace calcium as the mineral in bone. Because strontium atoms are heavier than calcium atoms, swapping some of the calcium atoms with strontium atoms will make the bone mineral density appear to increase.
