I'm an enthusiast with a deep understanding of the topic at hand. Let's delve into the fascinating world of bromine and its origin.
The name "bromine" has its roots in the Greek word "bromos," which translates to "stench." This is indicative of one of its characteristics. Bromine was discovered in 1825 at the University of Heidelberg in Germany and simultaneously at the Laboratory of Medicine and Chemistry in Montpellier, France. In Germany, it was Karl J. Lowig and Professor L. Gmelin who made the discovery, while in France, it was Antoine Jerome Balard.
Now, let's explore some key concepts related to bromine:

Sodium bromate (NaBr)
Interesting Facts:
Bromine is obtained from sea water.
It is a strong irritant that can cause skin blisters in concentrated forms.
Approximately 500 million kilograms of bromine are produced worldwide in a year.
Common Uses:
Brominated vegetable oil: Used in the food and beverage industry.
Citrus flavored soft drinks: Bromine can be found in these drinks.
Drug to aid in sleeplessness (no longer available in the United States): It was once utilized for this purpose.
Anti-knock products found in gasoline: Helps improve the octane rating of gasoline.
Fumigants: Used for pest control.
Poisons: Bromine compounds can have toxic properties.
Dyes: Bromine is used in the dyeing process.
Photographic chemicals: It plays a role in photography.
Medicines: Some pharmaceuticals contain bromine compounds.
Bromine's diverse applications in various industries make it a compound of significant importance. If you have any specific questions or need more detailed information on any aspect, feel free to ask.
Bromine is a chemical element; it has symbol Br and atomic number 35. It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine.
Let's use it to write the electron configuration of a neutral bromine atom, a bromine atom has 35 electrons. Using the blocks in the periodic table we can write the electron configuration of bromine as: 1s22s22p63s23p64s23d104p5.
In a neutral atom the number of protons = the number of electrons. 35 protons = 35 electrons. But Bromine anion with a charge of -1 has one extra electron so 35 +1 = 36 electrons.
The atomic number of Br (Bromine) is 35, which means it has 35 protons in its nucleus. The mass number of Br is 80, which means it has 80 nucleons (protons and neutrons) in its nucleus. So, Br has 35 protons, 45 neutrons, and 35 electrons (since the number of protons and electrons is the same in a neutral atom).
The atomic number of Bromine is 35. The electronic configuration of Bromine can be written as. The valence electrons are the sum of the electrons in the outermost shell, that is two electrons and five electrons which gives a total of seven valence electrons.
For Br, atomic number and atomic mass are given as 35 and 80 respectively. So, the number of electrons = the number of protons = 35. And, a number of neutrons = 80 - 35 = 45.
The element with the atomic number 35 is bromine (Br). There are 35 protons and 36 electrons in the given species, so the species will have a unit negative charge because there is one more electron than the number of protons present in the species.
Explanation: The atomic number for Bromine (Br) is 35, which means it has 35 protons. In a neutral atom, the number of electrons is also equal to the number of protons. However, as the bromine ion is negatively charged (Br -1), it has gained one electron, so there are 36 electrons.
Bromine's chemical symbol is Br and is part of the halogen group of the periodic table. The bromine substance Br2 is a reddish-brown liquid and is never naturally found in its elemental form but rather in inorganic compounds, also known as bromides, and in natural organo-bromine compounds.
bromine (Br), chemical element, a deep red noxious liquid, and a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. bromine.
