Question

Bromine is the only halogen and nonmetal that is normally in what state?

Answer 1

Hint: The halogens are a group of five chemically related elements in the periodic table. This group is designated as group 17 in contemporary IUPAC nomenclature. The word "halogen" literally means "salt-producing." When halogens react with metals, a variety of salts are produced, including calcium fluoride, sodium chloride, silver bromide, and potassium iodide. At normal temperature and pressure, the halogens are the only periodic table group that contains elements in three of the major states of matter.

Complete answer:
Bromine, a nonmetal in group 17 of the periodic table, is the third halogen. Its characteristics are therefore comparable to fluorine, chlorine, and iodine, and tend to be midway between the two neighbouring halogens, chlorine and iodine. Bromine has the electron configuration
\[[Ar]4{{s}^{2}}3{{d}^{10}}4{{p}^{5}}\]
 , with its valence electrons being the seven electrons in the fourth and outermost shell. It has one electron short of a full octet, like other halogens, and is thus a powerful oxidising agent, interacting with a variety of elements to complete its outer shell.
When halogens are linked to hydrogen, they all produce acids. The majority of halogens are produced from minerals or salts. Chlorine, bromine, and iodine, the middle halogens, are frequently employed as disinfectants. The most common type of flame retardant is organic bromides, but elemental halogens are hazardous and can be fatal.
Bromine is one of just a few elements that is liquid in its natural state. And bromine, or \[B{{r}_{2}}\] , is one of the most corrosive chemicals you may come into contact with. It may cause severe burns, thus its solutions, particularly the plain liquid, are handled with caution. At ambient temperature, bromine is the only non-metal that is liquid. Other than Mercury, it is one of only two elements on the periodic table that are liquids at ambient temperature. Bromine is a liquid due to strong intermolecular interactions that prevent it from evaporating. Bromine produces diatomic molecules with sufficient Van der Waals contacts.

Note:
Bromine is a highly reactive element that only occurs in nature as colourless soluble crystalline mineral halide salts, similar to table salt. The great solubility of the bromide ion ($B{{r}^{-}}$) has led to its buildup in the seas, despite its rarity in the Earth's crust. The element is easily mined commercially from brine pools, which are primarily found in the United States, Israel, and China. Bromine makes up roughly one-third of the mass of chlorine in the seas.
