| Bromine was discovered by Antoine J Balard in 1826. |
| It was used for important purposes long before it was formally discovered. |
| Two separate scientists isolated bromine, including one who was still in school. |
| Carl Lowig's school work prevented him from publishing his findings on bromine, leaving Balard to beat him to it. |
| Bromine does not occur naturally on Earth as an element. |
| Its salts are found in the crust at about .4 parts per million. |
| Bromine is only the 64th most common element on Earth. |
| It is more rare than three quarters of the elements that comprise the Earth's crust. |
| Bromine's easy solubility means it has built up in the oceans through leaching. |
| Most bromine produced is extracted from brine. |
| Typically, bromine is found as the diatomic Br2. |
| This Br2 is only found as bromide salts, never as pure bromine. |
| It is somewhat transparent, even though it is a dark, reddish color. |
| It evaporates easily under normal conditions. |
| Along with mercury, bromine is one of two elements found to be a liquid at room temperature. |
| Bromine reacts very strongly with most metals to produce bromide salts. |
| Bromine has two stable isotopes. |
| Br-79 makes up slightly more than 50% of all bromine found, and Br-81 makes up just over 49%. |
| There are 23 known radioactive isotopes of bromine. |
| The longest half-life of any known bromine radioisotope is 2.38 days. |
| Bromine was first used industrially to replace iodine vapor in the daguerreotype. |
| Two bromine compounds were used as sedatives and seizure medications in the 1800s and early 1900s. |
| Bromine was a component of World War I era poison gas. |
| Today, bromine plays a vital role in the production of flame retardant materials. |
| This brominated retardant is the current largest industrial use for bromine. |
| The US and Israel, typically extracted from the Dead Sea, are the world's two largest producers of bromine. |
