Which metal is used in making electrical fibres?(a) Actinium(b) Nickel(c) Thorium(d) TungstenThe question was asked by my college professor while I was bunking the class.My question is from Application of d and f-Block Elements topic in chapter D and F-Block Elements of Chemistry – Class 12

Answer» CORRECT choice is (d) TUNGSTEN

For EXPLANATION I WOULD say: The melting point of Tungsten (W) is very high (3422°C). It has the highest melting point among all the metals. This property of Tungsten makes it excellent for use as filaments in light bulbs as it can resist high TEMPERATURES.
