Acidic oxide - Howling Pixel

Acidic oxide. Acidic oxides, or acid anhydrides, are oxides that react with water to form an acid, or with a base to form a salt.They are oxides of either nonmetals or of metals in high oxidation states.Their chemistry can be systematically understood by taking an oxoacid and removing water from it, until only an oxide remains. The resulting oxide belongs to this group of substances.

2017-11-4 · General physical and chemical properties of chemical elements defines elements as non-metal. Every element in the periodic table can be termed either a metal or a nonmetal. (A few elements with intermediate properties are referred to as metalloids). Non-metals cannot be hammered or beaten into thin sheets without breaking. Non-metals break into pieces when hammered or stretched.
