There are 3 groups of non-metals in which they are : Halogens, Noble Gases and Other nonmetals
Oxygen is a nonmetal. Oxygen 2 is a molecule composed of two oxygen atoms, and like all oxygen atoms, it is classified as a nonmetal on the periodic table.
All materials are either metal, metalloid, or nonmetal.
Ionic bond is specific for metal-nonmetal combinations.
Fluorine is the most reactive nonmetal in period 2 of the periodic table.
Salt is a compound of Sodium (Na) and of Chlorine (Cl), thus, it is a nonmetal because it is a compound of 2 nonmetals. Na is not a nonmetal it is a highly active metal. This can be easily googled.
The groups of the periodic table are:Group 1: Alkali MetalsGroup 2: Alkali Earth MetalsGroup 3: BoronGroup 4: CarbonGroup 5: NitrogenGroup 6: OxygenGroup 7: HalogensGroup 8: Noble or Inert Gases
nonmetal
Fluorine, F, is in group 17 (7A) and period 2.
A substance which vibrates at a cyclical rate of -9.8m/s^2
Nails are metal.
Ionic compounds are compound consisting of a metal plus a nonmetal. The metal and the nonmetal both have charges that you can find on the Periodic Table, and they have to balance each other out. For example, you have MgO (Magnesium Oxide). The magnesium is the metal, the oxygen is the nonmetal, and they both have a charge of +2 and -2, so the subscripts cancel each other out.
