क्या कारण है कि हीरा कठोर एवं ग्रेफाइड चिकना एवं नरम होता है ?
Answers
Answer:
प्रत्येक कार्बन का चौथा इलेक्ट्रान मुक्त अवस्था में रहता है दो परतों के मध्य आकर्षण बल दुर्बल होने के कारण एक परत दूसरी परत पर आसानी से फिसल सकती है इसलिए ग्रेफाइट नर्म होता है। ... प्रत्येक कार्बन परमाणु अन्य चार कार्बन परमाणुओं से एक बंध से जुड़ा रहता है। इस त्रिविमीय संरचना के कारण ही हीरा कठोर होता है।
