Thus metal-oxide-based materials reveal a capability to adsorb ions  and because of that one of their major uses is for adsorbing metal or nonmetal ions from aqueous wastewater streams . In this work adsorption of harmful oxyanions by metal oxide-based materials according to a …
Magnesium metal is burned in nitrogen gas. Mg + N2 ( Mg3N2 Note: metal + nonmetal yields the salt Sulfur dioxide gas is passed over solid calcium oxide. SO2 + CaO ( CaSO3 Note: nonmetal oxide + metal oxide ( salt with polyatomic ion (no change in
13/12/2006· it is because Calcium is a metal, and oxygen is a nonmetal. When you coine a metal with a nonmetal to form a compound it is called an ionic compound. An ionic compound is when a ion (positively charged) and an anion (negatively charged) create a
Data for alkali metal germanate systems (up to approximately 0.4 mole fraction alkali metal oxide) yield the value Λ(GeO2) = 0.61 and basicity moderating parameter for Ge4+, γ, of 1.64.

Many metal oxides react with water to form alkaline hydroxides, e.g., calcium oxide (lime) reacts with water to form calcium hydroxide (slaked lime). Some metal oxides do not react with water but are basic in that they react with an acid to form a salt and water.
23/7/2018· For example, graphite and diamond are two allotropes of the nonmetal carbon, while ferrite and austenite are two allotropes of iron. While nonmetals may have an allotrope that appears metallic, all of the allotropes of metals look like what we think of as a metal (lustrous, shiny).
