Diatomic Nonmetal

In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes. Physically, nonmetals tend to be highly volatile (easily vaporized), have low elasticity, and are good insulators of heat and electricity; chemically, they tend to have high ionization energy and electronegativity values, and gain or share electrons when they react with other elements or compounds.

Fluorine Facts

2019/7/3Fluorine Trivia Fluorine in the form of the mineral fluorite was used in the 1500s to aid in ore smelting. Fluorine was suspected to be an element as early as 1810 but wasn't successfully isolated until 1886. Many chemists trying to isolate the element would be blinded or even killed by the violent reactions that generally accompany fluorine gas. Get price

The Complete Classification of Minerals

The nonmetal sulfur (S) and the semimetals selenium (Se) and tellurium (Te) consistently play the electronegative, anionic role in their compounds. However, the semimetals arsenic ( As ) and antimony ( Sb ) may either play the anionic role often filled by sulfur or else act as a cation by donating electrons and forming a compound with sulfur.
