Metalloids, also known as semimetals are elements containing properties similar and midway between metals and nonmetals. They are found to divide the periodic table between the metals on the left and the nonmetals on the right.
Metalloids often have the following properties:
- could be dull or shiny
- conducts heat and electricity, but not as well as metals
- good semiconductors
- usually malleable
- usually ductile
- can both gain and lose electrons in reactions
This is a list of the seven metalloid elements in order of increasing atomic number.
