What is a poor conductor of electricity? What happens to metal when heated and cooled? A certain element has its outermost electron in a 2s subshell. It has valence +1 because it has 1 more electrons than a certain noble gas. What element is it? Express your answer using its one- or ...
It was one of the first metals mined in North America, where it was sought after especially for making shot. Properties and Isotopes Lead is a dense, relatively soft, malleable metal with low tensile strength. It is a poor conductor of electricity and heat. Lead has a face-centered cubic...
Does Lead Conduct Electricity? “Although lead compounds can be good insulators, pure lead is a metal that conducts electricity, making it a poor insulator. Lead’s resistivity is 22 billionths of a meter. It sees use in electrical contacts because, being a relatively soft metal, it deforms...
Why are ionic solids poor conductors of heat and electricity although they are composed of charged particles? Compare the temperature dependence of electrical conductivity of a metal with that of a typical metalloid. Explain the difference. How does a fuel cell generate electrical en...

Get Allen’s Free One Shot Videos Free ALLEN One Shots Text SolutionVerified by Experts The correct Answer is:C Metals are good conductors of electricity due to the presence ...
Metals are elements that are lustrous, solid, opaque and high in density. The boiling and melting points of metals are very high. Also, they are the effective conductors of electricity and heat. They are ductile (can be drawn into thin wires) and malleable (beaten in thin sheets). As the...
Lead (atomic no. 82) is a bluish-white metal of bright luster, is soft, very malleable, ductile, and a poor conductor of electricity. Because of these properties and its low melting point (327°C), and resistance to corrosion, Pb has been used in the manufacture of metal products for ...
Copper is a great conductor, while rubber and air are poor conductors. Water can conduct electricity but not as well as metals like copper. Remember, every material is unique in its own way, just like every brushstroke on a canvas is special. Answer Chemistry Temperature Elements and Compounds...
