On earth, all elements are divided into three categories which are metals, metalloids, and nonmetals. Among all elements, some are essential while some metals, metalloids, or nonmetals are hazardous. Lethal or toxic heavy metals like arsenic, mercury, lead, selenium, etc. should be treated to...
Metalloidsare also known as semimetals. These elements have the properties of metals and nonmetals. Metalloids or semimetals play a role as semiconductors which are used in electronic devices and computers. In the periodic table, they are present in a zig-zag line between boron and aluminium and...
1 Properties of Metal, Nonmetals, and Metalloids Metals, Nonmetals and Metalloids • The individual atomic properties of atoms can be related to the observed macroscopic behavior of the elements. The trends we observe across the periodic table help explain chemical behavior. – Metals tend to ...

The determination of the localization and distribution of essential and beneficial metals (e.g., Cu, Fe, Zn, Mn, Co, Ti, Al, Ca, K, Na, Cr and others), toxic metals (like Cd, Pb, Hg, U), metalloids (e.g., As, Se, Sb), and non-metals (such as C, S, P, Cl, I) in...
How do metals and nonmetals bond? What elements on the periodic table are nonmetals? How do nonmetals form negative ions? Which property do metalloids share with nonmetals? Which nonmetals have similar chemical properties? When nonmetals react with metals, what happens to the atoms of the non...
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 conductivity properties (they only part...
