Facts about barium
Here are a few interesting facts about barium element.
- Barium was given its name from the Greek word “barys”, which means heavy.
- Carl Wilhelm Scheele discovered barium in 1772 and Humphry Davy was the person to isolate barium in 1808.
- Barium is the 17th most abundant element found from the earth’s crust.
- Our body also contains a trace amount and it is obtained from foods like onion, carrot, beans, etc.
Properties of barium
Here is a list of some physical properties and chemical properties of barium.
Physical properties of barium
- Barium has a silvery gray metallic luster having a pale yellow tint.
- Barium has a BCC crystal structure.
- The melting point and boiling point of barium is 1000 K and 2118 K respectively.
- There are many isotopes of barium, and out of those isotopes, the most abundant isotope is 138Ba.
- The barium has a density of 3.51 g/cm3 and its atomic mass is 137.33 amu.
Chemical properties of barium
- Barium is a reactive metal and because of this reason, it is always found as a compound with other elements.
- Barium reacts with water to form barium hydroxide.
- There are 2 valence electrons in barium and it loses these 2 valence electrons to become stable.
- Barium reacts with oxygen to form barium oxide.
Uses of barium
Here are some uses of the barium element.
- Barium is highly reactive to oxygen and because of this reason, barium is used to remove the oxygen gas present in the vacuum tubes.
- Barium nitrate and barium chlorate can produce green color, so they are used in fireworks.
- Various engine parts like spark plug, bearings, etc contain barium metal as an alloying element.
- Barium has an ability to absorb X-rays, so it is also used in X-rays absorber.
- Barium sulfate is used in making glass, rubber, drilling fluids, etc.
