Nonmetals Properties of Nonmetals Nonmetals occur to the right of the dark zig-zag on the periodic table. Although Hydrogen is in family 1, it is also a nonmetal. Many nonmetals are gases at room temperature. Properties of Nonmetals Nonmetals do not have luster; they are dull. Properties of Nonmetals Brittle Nonmetals are brittle so they break
Chemical Properties of Nonmetals. Non-metals have a tendency to gain or share electrons with other atoms. They are electronegative in character. Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions: Nonmetal + Metal -> Salt \[3Br_{2(l)} + 2Al_{(s)} \rightarrow

Answer is Ca which is a metal. Explanation: Milk is composed of many elements such as Calcium (Ca), Magnesium(Mg), Phosphorus(P), Potassium (K), Zinc(Zn) ans Selenium(Se).The major component present is Ca.. Calcium present helps in the formation of bones and teeth and maintaining it to keep healthy.. Elements which can loose electrons easily to obtain a stable configuration is called as a metal.
Examples of this egory are Tungsten carbide, aluminium carbide, calcium carbide,etc. These are generally prepared by reaction of the metal and the carbon at high temperatures or by reacting the metal oxide with graphite in a temperature range of 650-900°C. These have high MP and BP. These carbides have metallic properties and are refractory.
