0 a member of a group of five particular chemical elements:
Chlorine and iodine are halogens.
1 any of a group of five chemical elements that combine with hydrogen to make substances from which salts (= substances made with an acid) can be made
The halogens, with their large electron affinities, are the best negative ion candidates.
To prevent damage by the calorific source of the halogen lamp, during illumination the spinal cord was bathed with saline solution.
Second, the intensity of the tungsten halogen lamps could be reduced in order to lower the thermal heating of plant canopies.
However, this is not the case in the halogen light, and so we have to reflect this uncertainty into the distance reading.
There are perhaps two ways to solve the potential thermal issues with tungsten halogen lamps.
Although there are many electronegative elements, only the halogens have sufficiently large electron affinities to render current densities of this magnitude likely.
In the first volume, he had already covered the halogens and the alkaline metals.
We have no analyses for hydrogen and halogens, thus all analyses are based on 23 oxygens (46 negative charges in the silica-oxygen framework).
