2 days ago · Nonmetals are chemical elements that mostly lack distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine. Physically, they are usually lighter (less dense) than metals; brittle or crumbly if solid; and often poor conductors of heat and electricity.
3 days ago · Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust.

1 day ago · Metals and Non-Metals | Brilliant Math & Science Wiki. Sravanth C. and Skanda Prasad contributed. Chromium, a metal and sulfur, a non-metal. The periodic table can be broadly segregated into two types of elements, commonly referred to as metals and non-metals.
3 days ago · Equally, some materials regarded as metals can become nonmetals. Sodium , for example, becomes a nonmetal at pressure of just under two million times atmospheric pressure, though at even higher pressures it is expected to become a metal again.
Apr 1, 2024 · Metal, any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light. Approximately three-quarters of all known chemical elements are metals. Learn more about metals in this article.

Apr 10, 2024 · Lithium, chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale. Learn more about the occurrence and uses of lithium.
Apr 11, 2024 · radon (Rn), chemical element, a heavy radioactive gas of Group 18 ( noble gases) of the periodic table, generated by the radioactive decay of radium. (Radon was originally called radium emanation.) Radon is a colourless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen.
