Why is corrosion only a problem for some metals (such as iron)? Why metals react more vigorously in acids than in water? Explain why ionic solids do not conduct electricity in the solid state but are strong conductors in the liquid state and when dissolved in water. ...
Why do some metals conduct heat better than others? What causes their difference in heat conductivity? Explain why ionic solids do not conduct electricity in the solid state but are strong conductors in the liquid state and when dissolved in water. ...
Insulators (nonmetals) have a higher BE than metals, and it is more difficult for photons to eject electrons from insulators. Discuss how this relates to the free charges in metals that make them good conductors. Give the reasons that makes copper conduct electricity and heat better when...
But unlike carbon, silicon ametalloid --in fact, it's the most common metalloid on earth. "Metalloid" is a term applied to elements that are better conductors of electron flow -- electricity -- than nonmetals, but not as good as metals. What metals can bend without breaking? A: Theiro...
Why are alkali metals more reactive than alkaline-earth metals? How does metallic bonding structure explain why metals are malleable? Why does water boil at a higher temp then NH_3 when they are both dipoles? Why does the boiling point of liquids vary with altitude?
are stronger. b. are stable to much higher temperatures. c. have a lower density. d. are better electrical conductors. e. none o Which of the following are properties of metals? More than one answer is correct. (a) good conductor of electricity and heat (b) low density (...
Why do metals conduct heat and electricity? What are the physical properties of graphite? Why are metals good conductors of electricity? Why does cold metal conduct electricity better than warm metal? What is the best explanation for why graphite is slippery whereas diamond is not? a. Because ...
