What is Bromine as on the Periodic Table?

Definition of the Bromine Element
A heavy, volatile, corrosive, reddish-brown, non-metallic liquid element, having a highly irritating vapor. Bromine is the only non-metallic element that is liquid under ordinary conditions, it evaporates easily at standard temperature and pressures in a red vapor that has a strong disagreeable odor resembling that of
Chlorine.

Bromine gives off a red vapor that is extremely irritating to the eyes and the respiratory tract. Liquid bromine causes serious skin burns. It is used in producing gasoline antiknock mixtures, fumigants, dyes, and photographic chemicals. The Atomic Number of this element is 35 and the Element Symbol is Br.

 

What is Bromine? Origin / Meaning of the name Bromine
The
name originates from the from Greek word Bromos meaning "stench" due to its strong disagreeable odor.

What is Bromine? Periodic Table Group and Classification of the Bromine Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a liquid at room temperature.. Bromine
is classified as an element in the 'Halogens' section which can be located in group 7 of the Periodic Table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". The halogens exist, at room temperature, in all three states of matter - Gases such as Fluorine & Chlorine, Solids such as Iodine and Astatine and Liquid as in Bromine.

What is Bromine? Facts about the Discovery and History of the Bromine Element
Bromine was discovered by Antoine J. Balard in France in 1826, who isolated it from sea salt. He named it bromine (stench) because of its unbearable fumes.

What is Bromine? Occurrence of the Bromine Element
Bromine occurs almost entirely in the form of bromides, especially as
Sodium bromide and Magnesium bromide, which are found in many salt springs and salt deposits. The Stassfurt deposits in Germany and the salt waters of Ohio and Michigan are especially rich in bromides. Bromine occurs in nature as bromide salts in Sea Water
Primary producers - USA and Israel
