halogen | Facts, Definition, Properties, & Uses

Halogen elements are very reactive. They produce salts with sodium, of which table salt (sodium chloride, NaCl) is the most well-known. The halogen elements have seven valence electrons in their outermost electron shell. Therefore, when these elements can receive an electron from another atom, they form very stable compounds since their outermost shell is full.
