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 11
A student observed that a certain element is shiny, malleable, and conducts electricity. Is this element more likely to be a metal or a non-metal?
Describe the difference in the appearance of metals and non-metals.
Describe the difference in the type of ions formed by metals and non-metals during chemical reactions.
Describe two chemical properties that differentiate metals from non-metals.
Explain why metals are ductile but non-metals are not.
Explain why metals are good conductors of electricity.
Explain why non-metals do not conduct electricity, except for graphite.
Explain why sodium, a metal, is soft and can be cut with a knife, while iron is hard.
A student is given two elements: Element X is a solid that is a poor conductor of electricity and forms acidic oxides. Element Y is a shiny solid that reacts with dilute hydrochloric acid to produce hydrogen gas. Identify which element is a metal and which is a non-metal, and justify your answer based on their physical and chemical properties.
Compare the malleability and ductility of metals and non-metals, and explain the underlying reason for this difference at the atomic level.
Explain why non-metals are more likely to act as oxidizing agents in chemical reactions, while metals are more likely to act as reducing agents.
Explain, with reference to their electronic configurations, why metals tend to form cations while non-metals tend to form anions during chemical reactions.
State one reason why non-metals generally have lower melting and boiling points compared to metals.
