Halogens
Did you know certain elements help make light bulbs shine brighter and last longer? The answer lies with halogens, a group of elements in Group 17 of the periodic table.
This group includes fluorine, chlorine, bromine, iodine, and astatine, each with unique properties linked to everyday uses.
With seven valence electrons, halogens are highly reactive, eager to gain one more electron to complete their outer shell.
They exist in all states of matter at room temperature: fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
Halogens are also colorful. Fluorine is pale yellow, chlorine is greenish-yellow, bromine is reddish-brown, and iodine in gas form is purple-black.
These elements combine with metals to form salts, like the sodium and chlorine in table salt.
Halogens are vital in daily life. Fluorine in toothpaste strengthens teeth, chlorine and bromine purify water, and iodine disinfects wounds.
Their reactive nature also makes them dangerous. Fluorine and chlorine gases are toxic and must be handled carefully.
