How did strontium get discovered?
Strontium metal itself was isolated in 1808 at the Royal Institution in London by Humphry Davy by means of electrolysis, using the method with which he had already isolated sodium and potassium.

How does strontium react with water?
Strontium reacts with water slowly, generally to strontium hydroxide and hydrogen gas. It reacts with water quicker than calcium, which is placed directly above strontium in the periodic chart, and slower than barium, placed directly below strontium.
Why strontium is called a bone seeker?
Strontium-90 behaves like calcium in the human body and tends to deposit in bone and blood- forming tissue (bone marrow). Thus, strontium- 90 is referred to as a “bone seeker,” and exposure will increase the risk for several diseases including bone cancer, cancer of the soft tissue near the bone, and leukemia.
Why does Sr burn red?
A scarlet-red color is imparted to the flame by strontium chloride. Metal salts introduced into a flame give off light characteristic of the metal. Metal ions combine with electrons in the flame and the metal atoms are raised to excited states because of the high flame temperature.
Is SROH soluble in water?
According to handbook data (Merck index and CRC handbook) strontium hydroxide is very soluble in water (>10g/L) at 25°C.
Why does magnesium react slowly with water?
However, the reaction is short-lived because the magnesium hydroxide formed is almost insoluble in water and forms a barrier on the magnesium preventing further reaction. As a general rule, if a metal reacts with cold water, the metal hydroxide is produced. If it reacts with steam, the metal oxide is formed.
Is radium a bone seeker?
Because of its preference for bone, radium is commonly referred to as a bone seeker. Various radiation effects have been attributed to radium, but the only noncontroversial ones are those associated with the deposition of radium in hard tissues.
