What is the Abbreviation for Strontium?

The abbreviation for strontium is Sr. This chemical symbol, universally recognized by scientists and engineers, derives from the element's name. Remembering this simple abbreviation is crucial for understanding chemical formulas and equations involving strontium.

Strontium: Key Properties and Characteristics

Strontium (Sr), atomic number 38, is a silvery-white alkaline earth metal. Its key properties include:

Atomic Number: 38
Atomic Weight: 87.62 u
Melting Point: 777 °C (1431 °F)
Boiling Point: 1382 °C (2519 °F)
Density: 2.64 g/cm³
Reactivity: Highly reactive with water and air.

Its reactivity makes it crucial to handle strontium with care. Exposure to air causes rapid oxidation, forming a dull oxide layer. Reaction with water produces strontium hydroxide and hydrogen gas.

Strontium Isotopes

Naturally occurring strontium is a mixture of several isotopes. The most abundant are strontium-88 (82.6%), strontium-87 (7.0%), and strontium-86 (9.9%). Radioactive isotopes like strontium-90 are produced through nuclear fission and pose environmental and health concerns.

Applications of Strontium: Where is it Used?

Strontium's unique properties make it valuable in diverse applications. Some key uses include:

1. Fireworks and Pyrotechnics

Strontium compounds, particularly strontium carbonate (SrCO₃), impart a brilliant red color to fireworks. This is a classic application, relying on the element's ability to emit red light when heated.

2. Medical Imaging

Strontium-89 is used in the treatment of bone cancer. It targets bone metastases, offering palliative relief. [Link to a reputable medical source on Strontium-89 use].

3. Metallurgy and Alloys

Strontium is added to aluminum and magnesium alloys to improve their strength and machinability. This enhances the properties of these metals in various industrial applications.

4. Refining of Zinc and Lead

Strontium is utilized to refine zinc and lead, enhancing the purity of these metals. The process improves the overall quality and usability of these refined materials.

5. Other Uses
