What is BA on the periodic?
barium (Ba), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table.
Is barium harmful to humans?
The Ba2+ ion and the soluble compounds of barium (notably chloride, nitrate, hydroxide) are toxic to humans. Although barium carbonate is relatively insoluble in water, it is toxic to humans because it is soluble in the gastrointestinal tract.
What was barium originally used for?
vacuum tubesBarium was identified as a new element in 1774, but not reduced to a metal until 1808 with the advent of electrolysis. Barium has few industrial applications. Historically, it was used as a getter for vacuum tubes and in oxide form as the emissive coating on indirectly heated cathodes.
What is Br in periodic table?
Bromine - Element information, properties and uses | Periodic Table.
What foods have barium in them?
Some foods, such as Brazil nuts, seaweed, fish, and certain plants, may contain high amounts of barium. The amount of barium found in food and water usually is not high enough to be a health concern.
Where is barium most commonly found?
Barium is most commonly found as the mineral barite (BaSO4) and witherite (BaCO3) and is primarily produced through the electrolysis of barium chloride (BaCl2). Barium is used as a getter, a material that combines with and removes trace gases from vacuum tubes.
Is barium a toxic metal?
Introduction: Barium is a stable divalent earth metal and highly toxic upon acute and chronic exposure.

What are 5 common uses of barium?
Barium compounds are used by the oil and gas industries to make drilling mud. Drilling mud simplifies drilling through rocks by lubricating the drill. Barium compounds are also used to make paint, bricks, tiles, glass, and rubber. Barium nitrate and clorate give fireworks a green colour.
Is bromine a nonmetal?
Bromine is a dark, reddish-brown liquid at room temperature (the only nonmetallic element that is a liquid at room temperature) with a terrible smell.
Is bromine water toxic?
Causes severe eye irritation and possible burns. Skin: Causes skin irritation and possible burns. Ingestion: Causes severe digestive tract burns with abdominal pain, vomiting, and possible death. Inhalation: Irritation may lead to chemical pneumonitis and pulmonary edema.
Why halogens are called halogens?
They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of similar properties, of which sodium chloride—table salt, or halite—is best known.
How much barium is harmful?
NIOSH considers exposure to barium chloride levels of 50 mg/m3 and higher as immediately dangerous to life or health.
How long does barium stay in your body?
It's a good idea to drink a lot of fluids for a few days to flush out the barium. For 1 to 3 days after the test, your stool (feces) will look white from the barium. If the barium stays in your intestine, it can harden and cause a blockage.
How much barium is toxic?
Toxic dose. The US Environmental Protection agency (EPA) has set an oral reference dose for barium of 0.07 mg/kg/d. A level of 50 mg/m3 may be immediately dangerous to life and health (IDLH).
How does the body get rid of barium?
You can manage constipation by drinking plenty of fluids and eating foods high in fiber to help the rest of the barium leave your body. You may also be given a laxative to help with this. Your bowel movements may be white or lighter in color until all the barium has left your body.
Occurrence
Physical Properties
- Pure barium is a silvery-white shiny malleable metal. It is comparatively dense and reactive alkaline earth metal. It has a melting point of about 725°C and a boiling point of about 1,640°C. Its density is 3.6 grams per cubic centimeter. When heated, barium compounds give off a pale yellow-green flame. Barium has specific weight and good electrical conductivity. The atomic nu…
Chemical Properties
- Barium chemically resembles, magnesium calcium and strontium but is more reactive. Reaction with chalcogens are highly exothermic. It combines easily with oxygen, the halogens, and other non-metals also reacts with water and most acids. It is so reactive that it must be stored under kerosene, petroleum, or some other oily liquid to prevent it from ...
Compounds
- Barium salts are white when solids and colorless when dissolved. They are denser than strontium or calcium analogs except for halides. Barium hydroxide unlike calcium hydroxide absorbs little CO2in aqueous solution insensitive to atmospheric fluctuation. Volatile barium compound burns with a green to pale green flame.
Uses and Significance
- Used to remove unwanted gases from vacuum tubes such as TV pictures tubes.
- Barium sulfate is important in petroleum industry as drilling fluids in oil and gas wells.
- It is widely used in making barium-nickel alloys in spark-plug electrodes.
- It is used in making fluorescent lamps.
Health Effects
- The health effects of barium are due to its water-solubility and water-soluble barium compounds can be harmful to human health. The intake of barium that are water-soluble may cause paralyses and in rare cases can also lead to death. When exposed to barium-contaminated water, a person can experience shallow breathing, increased blood pressures, irritation in stomach, weakness in …
Isotopes
- Barium has about 50 known isotopes ranging from 114 to 153. Most stable isotope is Barium-133 with half- life of approximately 10.51 years. Barium-130 undergo very slow reactive decay. Barium- 132 half -life thousand times greater than the age of the universe. Barium -138 lighter isotope and less abundant. Barium also has meta states out of which barium-133m1 has half –life of about …
