Chromate metal or nonmetal
WebFixed Charge Metal: metal name + nonmetal name + “ide” Variable Charge Metal: metal name (charge of metal) + nonmetal name + “ide” Don’t change the name for polyatomic ions to end in ide. For variable charge metals use a Roman Numeral to indicate the metal’s charge. How do you figure out the charge on a variable charge metal? WebNon-metals are often said to have five properties in common, however, not all non-metals possess all of these properties. While most non-metals have a low melting point, salt, for example, has a very high melting point of 801 °C. Despite the exceptions, the generally accepted properties of non-metals are: 1.

The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
WebNitrogen’s position in the periodic table ( group 15) reveals that it is a nonmetal. Nonmetals form negative ions (anions). A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−.
