Why is silicon a nonmetal?
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.
5 days ago · It is commonly regarded as a metalloid, or by some other authors as either a metal or a non-metal. It exhibits poor electrical conductivity which, like a metal, decreases with temperature. It has a relatively open and partially covalent crystalline structure (BCN 3+3).
5 days ago · rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 ( scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table ( cerium [Ce] through lutetium [Lu]).
3 days ago · It is also known as the "quintessential nonmetal" because it has similar properties to metals in some ways but not all. Properties of Silicon. A crystalline solid, silicon has a blue-gray metallic luster.

- 4. Where can you find silicon?Silicon comes from the Earth's crust and atmosphere. It is mined on land and overseas in China, Germany, South Africa, and the United States.
- 5. Is silicon a metal, nonmetal, or metalloid?Silicon is a semiconductor and not metal. It does not form any positive ions in the ground state and has low electrical conductivity in its pure form.
6 days ago · Nonmetals tend to gain electrons to form negative ions; Number of protons remains the same when ions are formed; The charge is determined by the difference in the number of protons and electrons in an atom; Example: Chlorine has 17 electrons and 17 protons when it is neutral; Example: Chlorine negative 1- ion has 18 electrons but 17 protons.
4 days ago · Phosphate is the name of the polyatomic ion which has a 3- charge. The ratio of manganese ions and phosphate ions must be such that the total charge is neutral. Use parentheses to indicate when there is more than one polyatomic ion. The positive ion is written first, followed by the nonmetal. Answer: Mn 3 (PO 4) 7; Write the formula for ...
