Question

Which one of the following is not a metal?
A. Iron
B. Silicon
C. Aluminium
D. Copper

Answer 1

Hint: We need to know that a metal is a material that, when newly ready, cleaned, or broken, shows a shiny appearance, and behaves power and warmth moderately well. Metals are ordinarily flexible or pliable. A metal might be a synthetic component like iron; a composite like treated steel; or an atomic compound like polymeric sulfur nitride.

Complete answer:
We have to know that, a non-metal is a substance component that for the most part does not have the attributes of a metal. Genuinely, a nonmetal will in general have a moderately low dissolving point, limit, and density. A nonmetal is ordinarily weak when strong and typically has helpless warm conductivity and electrical conductivity. Synthetically, nonmetals will in general have moderately high ionization energy, electron proclivity, and electronegativity. They gain or offer electrons when they respond with different components and synthetic mixtures. Seventeen components are by and large named nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a fluid (bromine); and a couple are solids (carbon, phosphorus, sulfur, selenium, and iodine). Metalloids like boron, silicon, and germanium are now, and again considered nonmetals.
Therefore, silicon is a non-metal.

So, the correct answer is “Option B”.

Additional information:
As we know that silicon is named a metalloid in light of the fact that a portion of its properties look like the properties of metals and a portion of its properties take after those of nonmetals. Metalloids are compound components whose properties lie in the middle of the average properties of metals and nonmetals.

Note:
We have to know that, the nonmetals are isolated into two classes mirroring their overall affinity to frame substance compounds: responsive nonmetals and honorable gases. The receptive nonmetals shift in their nonmetallic character.
