What are metals? Learn the definition and different types of metals. See the reactivity and examples of metals present in the periodic table.
The nonmetals in the periodic table. Metalloids The elements that border the stair-stepped line are classified as metalloids. The metalloids, or semimetals, have properties that are somewhat of a cross between metals and nonmetals. Metalloids tend to be economically important because of their unique...

While the underlined elements are sometimes called metalloids, it is has been known for over 100 years that metalloids predominately behave chemically like nonmetals. Astatine would’ve been a nonmetal but for relativistic effects. Immediately following its production in 1940, early investigators consi...
Metalloids can take on either a positive or negative charge, depending on what other elements are around. These elements are particularly important for theelectronic community. Nonmetalsrepresent thetop rightof the periodic table. These elements are usually gases at room temperature and tend to form...
