3. Metals and Non-metals
medium
आपको एक हथौड़ा, बैटरी, बल्ब, तार एवं स्विच दिया गया है:
$(a)$ इनका उपयोग कर धातुओं एवं अधातुओं के नमूनों के बीच आप विभेद कैसे कर सकते हैं?
$(b)$ धातुओं एवं अधातुओं में विभेदन के लिए इन परीक्षणों की उपयोगिताओं का आकलन कीजिए।
Option A
Option B
Option C
Option D
Solution
$(a) $ With the hammer, we can beat the sample and if it can be beaten into thin sheets (that is, it is malleable), then it is a metal otherwise a non-metal. Similarly, we can use the battery, bulb, wires, and a switch to set up a circuit with the sample. If the sample conducts electricity, then it is a metal otherwise a non-metal.
$(b)$ The above tests are useful in distinguishing between metals and non-metals as these are based on the physical properties. No chemical reactions are involved in these tests.
