Definition of bromine in English: brominenoun ˈbrəʊmiːnˈbroʊmin mass nounThe chemical element of atomic number 35, a dark red fuming toxic liquid with a choking, irritating smell. It is a member of the halogen group and occurs chiefly in the form of salts in seawater and brines. （化学元素）溴（符号： Br ） Example sentencesExamples - ‘While chlorine and bromine chemicals cause the ozone hole, temperature is also a key factor in ozone loss,’ Newman said.
- Other nations have signed since then, and recent studies indicate that the levels of bromine, another ozone-destroying chemical, are actually dropping.
- The spa's thermal waters, which bubble out of the ground at 38 degrees centigrade, have a high incidence of sulphate sodium, bromine and iodine and are particularly beneficial for those with respiratory conditions.
- The ozone depleting compounds contain combinations of the elements chlorine, fluorine, bromine, carbon and hydrogen.
- The elements that appear enriched from measurements that Spirit took with her alpha particle x-ray spectrometer are potassium, phosphorous, sulfur, chlorine, bromine.
- So, in the Lounge, we are reminded that computers, TVs, and radios contain such deadly things as cadmium, arsenic, bromine, and lead mercury.
- Then there was chlorine, bromine, and iodine: pungent, poisonous, and coloured gases.
- Jacob Berzelius immediately denominated chlorine, bromine, and iodine as ‘halogens’ or elements that form salts.
- The proportion of bromine to other chemically similar elements, like chlorine, varied by a factor of 10 from place to place.
- Allenes are prepared by the removal of bromine and hydrogen bromide from 1,2, 3 tribromopropane and its derivatives under the action of potassium hydroxide, zinc, and ethanol.
- Dry chlorine, iodine, bromine and fluorine cause little or no corrosion of magnesium at room or slightly elevated temperature.
- The two main ingredients are reactive halogen gases such as chlorine or bromine and sunlight.
- Along with carbon, they include elements such as hydrogen, oxygen, fluorine, chlorine, bromine, sulphur or nitrogen.
- Fluorine, chlorine, and bromine are all more chemically reactive than iodine; when in the body, they all tend to disrupt stable iodine molecules, displacing the iodine and causing its excretion.
- Organohalogens are organic compounds that contain one or more halogen atoms (fluorine, chlorine, bromine or iodine).
- While chlorine and bromine chemicals cause the ozone hole, extremely cold temperatures, especially near the edge of Antarctica, are also key factors in ozone loss.
- Mercury is the only liquid metal and the only liquid element except for bromine.
- The halogens are a group of chemical elements that includes fluorine, chlorine, bromine, iodine, and astatine.
- Recent experiments have begun identifying oxidizing gases, such as ozone and molecules containing the halogens bromine and chlorine, as triggers for that mercury fallout.
- For instance, electronegativities in the halide sequence fluorine, chlorine, bromine, and iodine decrease from fluorine through iodine.
