Physical and Chemical Differences Between Metals and Non-metals starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Physical and Chemical Differences Between Metals and Non-metals.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
Describe the difference in the density of metals and non-metals.
Describe the difference in the formation of ions by metals and non-metals.
Describe the difference in the physical state of metals and non-metals at room temperature.
Describe the difference in the reaction of metals and non-metals with acids.
Explain why metals are good conductors of electricity.
Explain why metals are malleable and ductile, but non-metals are not.
Explain why non-metals are generally poor conductors of electricity.
Explain why non-metals do not form alloys easily.
A sample of an unknown element is found to be a poor conductor of heat and electricity, is brittle, and forms acidic oxides. Based on these properties, classify the element as a metal or non-metal and justify your answer.
A student is given two elements: one is shiny, malleable, and reacts with hydrochloric acid to produce hydrogen gas; the other is brittle, dull, and does not react with hydrochloric acid. Identify which is a metal and which is a non-metal, and justify your answer based on their physical and chemical properties.
Compare the behavior of metals and non-metals when placed in dilute hydrochloric acid. What observations would you expect, and what do these observations indicate about their chemical properties?
Explain why non-metals generally have higher electronegativity values than metals, and how this affects their chemical behavior.
Explain, with examples, how the difference in electronegativity between metals and non-metals affects the type of chemical bonds they form.
