How do halogens form table salt and similar compounds?
ChemistryPeriodic Table
Quick Answer
Halogens tend to gain one electron, making them highly reactive nonmetals. They readily form salts with metals, such as sodium chloride, the main compound in table salt.
The Full Story
The halogens—fluorine, chlorine, bromine, iodine, and astatine—are in Group 17. They have seven valence electrons, so they often need just one more to complete their outer shell. This makes them strong oxidizing agents and very reactive with metals. Sodium and chlorine combine to form sodium chloride, which crystallizes into the familiar cubic salt structure.
Key Facts
1.Halogens are in Group 17
2.They typically gain 1 electron
3.Sodium chloride is NaCl
