halogens
Synonyms
Examples
As with other halogens, the bromide ion is colorless and forms a number of transparent ionic mineral salts, analogous to chloride.
Characteristics Chemical The halogens show trends in chemical bond energy moving from top to bottom of the periodic table column with fluorine deviating slightly.
Chemical Bonding, Mark J. Winter, Oxford University Press, 1994, ISBN 0-19-855694-2 Hydrogen, like the alkali metals, has one valence electron and reacts easily with the halogens but the similarities end there.
Halogens While the halogens aren't nucleophilic in their diatomic form (i.e. I 2 is not a nucleophile), their anions are good nucleophiles.
Chlorine is by far the most abundant of the halogens in seawater, and the only one needed in relatively large amounts (as chloride ions) by humans.
Compounds of chlorine with other halogens are colored, as are many chlorine oxides.
