What does BA stand for in chemistry?

barium (Ba), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table.

What is BR minus in chemistry?

Elemental bromine is very reactive and thus does not occur free in nature, but in colourless soluble crystalline mineral halide salts, analogous to table salt. While it is rather rare in the Earth’s crust, the high solubility of the bromide ion (Br−) has caused its accumulation in the oceans.

What bromine is used for?

Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire). Some bromine-containing compounds were historically used as sedatives (drugs that can make people calm or sleepy).

Is bromine and bromide the same?

Bromine is a chemical element of the halogen group, which includes fluorine, chlorine, iodine and astatine. Bromide is an anion of bromine, commonly found in trace amounts as salt in sea-water, along with sodium chloride (common table salt).

What is Br2 called?

Bromine | Br2 – PubChem.

Is Br negative or positive?

A bromide ion is the negatively charged form (Br−) of the element bromine, a member of the halogens group on the periodic table.

Is chemistry a BS or BA?

A BS in chemistry provides a certified curriculum with substantial research experience, while a BA in chemistry provides a solid chemistry core within a flexible curriculum.

Should I do BA or BS in chemistry?

If you’re planning to go into the biochemistry or organic chemistry fields, a Bachelor of Science degree is the better option. This type of degree might also be necessary if you want to become a doctor, veterinarian or dentist. Research-driven careers in chemistry or medicine also require a B.S. in chemistry.

Is a Bachelor of Arts in chemistry worth it?

A B.A. degree in chemistry provides a wide variety of career opportunities in areas as diverse as the chemical industry, the petroleum industry, the food industry, pharmaceuticals, mining, environmental analysis, and cosmetics, as well as many others.

Is bromine water toxic?

Harmful if inhaled. Causes respiratory tract irritation and possible burns. Causes eye and skin irritation and possible burns.

Is bromine a metal or nonmetal?

Smelly element No. 35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature, and one of only two elements (the other being mercury) that is liquid at room temperature and pressure.

Is bromine a chlorine?

What is Bromine? Bromine is the number one alternative to chlorine. This chemical is known to be a sanitizer, oxidizer, and algaecide for swimming pools. The reason why spa and hot tub owners prefer bromine over chlorine is that it works better in warmer temperatures.

Is Br a halogen or noble gas?

The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

Is Br a halogen?

Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

Why are they called alkali metals?

The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide. Alkalies are very strong bases that are caustic.

What is another word for bromide?

Similar words for bromide: banality (noun) bore (noun) chemical (noun) cliche (noun)

What happens if you drink bromine?

Ingestion of liquid bromine can cause abdominal pain and hemorrhagic gastroenteritis with secondary shock. Signs and symptoms might also include brown discoloration of mucous membranes and the tongue (1, 2).

Why did Canada ban bromine?

Salt systems using sodium bromide have been flagged as a health risk by Health Canada. Because of this, manufacturers will no longer offer parts or supplies to support these kinds of salt systems.

Why is bromine written as Br2?

Answer and Explanation: As a result, bromine is naturally found in groups of two making it a diatomic molecule. To communicate this, we write a subscript 2 with the symbol.

Is Br2 a compound?

The subscript indicates that 2 bromine atoms are bonded together. This is not a compound because the atoms are from the same element. This is simply a molecular element, also known as a diatomic molecule. It is common for all halogen elements in main group 7A (group 17) of the periodic table.

What type of compound is Br2?

Br2 is a diatomic molecule having two bromine atoms is a linear-shaped structured compound. Having the same electronegativity of both atoms, both share an equal proportion of charge. The atoms forming a covalent bond having equal electronegativity are nonpolar in nature.

Is Br2 an ionic compound?

Is Br2 a gas or liquid?

Bromine (Br, element 35), also found as a diatomic molecule (Br2), is a liquid at room temperature, solidifying at -7.2ºC.

Is Br2 a base?

Br2 and Br+ are soft Lewis acids and Br- has properties in between soft bases and hard bases. Hence Br2 is considered to be a soft Lewis acid.

What charge is Br?

The most stable oxidation state of the element is −1, in which bromine occurs naturally. But oxidation states of 0 (elemental bromine, Br2), +1 (hypobromite, BrO−), +3 (bromite, BrO−2), +5 (bromate, BrO−3), and +7 (perbromate, BrO−4) are also known.
