Explain why magnesium metal is more reactive than aluminum metal even though they are in the same period of the periodic table. Explain why calcium is more reactive than magnesium yet they are in the same chemical group. Why is copper (II) sulfate solution a good conductor of electricity?
Q1: Give the physical and chemical properties of metals and non-metals. Answer: The following are some of the physical properties of metals: Nature is lustrous (shiny). Metal is an excellent heat and electrical conductor. The melting point and density are both high. Ductile Mouldable (Malleable...
The meaning of NONCONDUCTOR is a substance that conducts heat, electricity, or sound only in very small degree.
Is a diamond a metal, nonmetal, or metalloid? Solid copper wire is a good conductor because Does astatine conduct electricity? Why do nonmetals gain electrons? Do nonmetals react with acid? How are metals different from nonmetals? Are nonmetals gases at room temperature?
Q.9. Assertion (A): Iron is the most widely used metal.But it is never used in its pure state. Reason (R): Pure iron is very soft and stretches easily when hot. Q.10. Assertion (A): All non metals are insulators. Reason (R): Graphite is a good conductor of electricity...
