Non-metals are generally brittle and hence cannot be beaten into sheets or … Chemical properties of nonmetals Non-metals are also called electronegative elements because the non-metal atom form negatively charged ion by accepting electrons. Chemical Properties of Metals. METAL + OXYGEN – METALOXIDE. Metals react with water differently to produce oxides and hydroxide. Nonmetals are poor conductors of heat and electricity. Metals . These properties apply to the metals in general (alkali metals, alkaline earth, transition metals, basic metals, lanthanides, actinides) and nonmetals in general (nonmetals, halogens, noble gases). Your email address will not be published. There are exception to this. On the periodic table, metals are separated from nonmetals by a zig-zag line stepping through carbon, phosphorus, selenium, iodine, and radon.These elements and those to the right of them are nonmetals. Sodium and potassium are exceptions in this case as they can be cut by a knife. 5. Most elements are metals. Non-metals are … 5.
