Uses of strontium
Strontium is a metal that is added to other metals to create alloys, and its radioactive isotopes have many applications. Chemically active strontium and its compounds have a wide variety of uses. If you’ve ever wondered what strontium is for , here is a list of its possible uses:
- The front display glass of CRT devices contains strontium compounds to prevent X-ray emission. This is the most common use of strontium.
- Strontium is often added with small amounts of aluminum and silicon creating alloys to improve its strength.
- AJ62 is a strong alloy used in the automotive industry that contains 2 percent strontium.
- Strontium is used in scientific research to measure the release of neurotransmitters from neurons. The reaction of calcium with strontium is what makes it easy to observe the response of the neuron.
- Radioactive strontium is used in radiopharmaceuticals to treat metastatic bone cancer. Sites that are experiencing laundry bone growth charges the absorption of strontium rather than calcium.
- Radioactive strontium is used as an energy source for thermoelectric generators. Strontium 90 is a common choice for this application as it is produced as a residue from nuclear reactions.
Strontium atomic properties
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find strontium within the periodic table of the elements, strontium is in group 2 and period 5. Strontium has an atomic mass of 87.62 u.
The electronic configuration of strontium is [Kr] 5s2. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The atomic radius or Bohr radius of strontium is 219 pm, its covalent radius is 195 pm, and its Van der Waals radius is 249 pm.
