A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry .
May 8, 2023 · What distinguishes metals, nonmetals, and semi-metals is the way electrons move between the bands: In metals (conductors), the two bands overlap, so when energy (in the form of heat or electricity) is added to the material, electrons are readily promoted from the valence band to the conduction band and carried through the material, giving rise ...
Difference Between Metals and Nonmetals- The elements present on the extreme right side of the periodic tables are non-metal, About 80 of the 105 elements in the periodic table are regarded as metals.

Iron. Iron is a chemical element; it has symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core.
An early use of the term heavy metal dates from 1817, when the German chemist Leopold Gmelin divided the elements into nonmetals, light metals, and heavy metals. Light metals had densities of 0.860–5.0 g/cm 3; heavy metals 5.308–22.000. The term later became associated with elements of high atomic weight or high atomic number.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
Selenium is a chemical element; it has the symbol Se and atomic number 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. [9] It seldom occurs in its elemental state or as pure ore ...
