Facts for Kids

Strontium is a shiny, silver-white metal that is found in the earth! 🌍

It sits in the same group of the periodic table as calcium. Strontium has the atomic number 38, which means it has 38 protons in its nucleus. The metal was discovered in 1790 by a Scottish chemist named William Cruickshank in a place called Strontian, Scotland. The name “strontium” comes from this village! Strontium is often used in fireworks, which makes the color red! 🎆

Isn’t that amazing? Strontium is also very reactive and doesn’t like to be exposed to air for too long.

Strontium plays a role in our bones! 🦴

Just like calcium, strontium can help strengthen bones. It works alongside calcium to provide stability and help our bones stay strong. When we consume foods rich in calcium, we can also get some strontium from our diets. 🎉

Foods such as spinach and legumes contain small amounts of strontium. However, it is essential to know that too much strontium isn’t healthy for us, so we have to get the right amount from our food!

Strontium belongs to a group of metals called alkaline earth metals. This group includes beryllium, magnesium, calcium, and radium. 💪

Strontium is very shiny when fresh but can turn dull when exposed to air because it forms a layer of oxide. Strontium reacts quickly with water and can create strontium hydroxide, which is a strong base! When heated, strontium burns with a bright red flame. 🔥

This property is why it’s used in fireworks. On the Mohs scale of hardness, strontium rates a 3, which means it can be scratched by a knife.

Strontium can impact the environment, especially during mining. When strontium is extracted from the earth, it can change the habitats of plants and animals. 🌱

It's essential that mining companies take care of the environment while extracting materials. Some isotopes of strontium can be radioactive, like strontium-90, which can be harmful if it enters the soil or water. 🚱

To keep our planet safe, scientists monitor the levels of strontium in ecosystems to ensure that nature and human activities can coexist!

Strontium can be found in nature, mainly in minerals like celestine and strontianite. 🌿

It is most commonly found in places like Europe and the United States. Strontium isn’t found as a free element in nature; it only appears as part of compounds. The largest deposits of celestine can be found in countries like Mexico and the UK. Strontium is often extracted from the earth through mining. 🌍

After mining, strontium is purified to get the shiny silver metal we can use for different applications, like fireworks and electronics!

Strontium has several different isotopes, but the main ones are strontium-84, strontium-86, strontium-87, and strontium-88. Isotopes are variations of the same element that have different numbers of neutrons. For example, strontium-88 is the most abundant isotope and has 50 neutrons. 📊

Strontium-87 is important in geology because it helps scientists understand how rocks formed over time! 🪨

Each isotope behaves a bit differently, which makes them special for various uses in research and science.

Doctors sometimes use strontium in medicine, especially strontium-89, for treating certain cancers. This helps manage pain for people with bone cancer. 💊

Strontium can target diseased bones while minimizing effects on healthy ones. Moreover, strontium ranelate is a medication that helps prevent osteoporosis, a condition that weakens bones. 🦴

This treatment helps many people keep their bones strong. Scientists are constantly researching new ways to use strontium in medicine to help people feel better!

Strontium has a unique history! After its discovery in 1790 in Strontian, Scotland, people began to see its importance. Strontium was used in metal alloys during World War II for various applications. 🌍

In the 20th century, strontium-90 became known because of nuclear fallout, which made scientists study its effects on health and the environment more closely. This led to a greater understanding of radioactive elements. Today, strontium continues to play a key role in science, medicine, and technology. What a remarkable journey! 🚀

Strontium has many cool uses! 🧪

One of the most exciting uses is in producing fireworks! It gives a brilliant red color to the fireworks. 🎆

It’s also used to make certain kinds of glass, such as in color television tubes. Strontium compounds are used in dental products to help protect against sensitivity! 🦷

Additionally, strontium is essential in creating special ceramics used in electronics. These materials help our devices work better! It’s incredible how one element can be so useful in different fields!
