New Latin, from Medieval Latin Polōnia Poland; named in honour of the Polish nationality of its discoverer, Marie Curie.
अंग्रेज़ी में POLONIUM का क्या अर्थ होता है?
एक विशेष तत्त्व जिस का प्रभाव रेडियो पर पड़ता है
पोलोनियम एक रासायनिक तत्व है जिसमें पीओ और एटॉमिक नंबर 84 के प्रतीक हैं, जो 18 9 8 में मैरी क्यूरी और पियरे क्यूरी द्वारा खोजा गया था। कोई स्थिर आइसोटोप वाला कोई दुर्लभ और अत्यधिक रेडियोधर्मी तत्व, पोलोनियम रासायनिक रूप से विस्मुट और टेल्यूरियम के समान है, और यह यूरेनियम अयस्क में होता है। पोलोनियम के अनुप्रयोग कुछ हैं, और अंतरिक्ष जांच, एंटीटैक्ट डिवाइस, और न्यूट्रॉन और अल्फा कणों के स्रोतों में हीटर शामिल हैं। आवधिक तालिका में अपनी स्थिति के कारण, पोलोनियम को कभी-कभी मेटलॉइड के रूप में वर्गीकृत किया जाता है। अन्य स्रोतों का कहना है कि इसके गुणों और व्यवहार के आधार पर, यह "निर्विवाद रूप से एक धातु" है।
अंग्रेज़ीशब्दकोश में polonium की परिभाषा
शब्दकोश में पोलोनियम की परिभाषा एक बहुत ही दुर्लभ रेडियोधर्मी तत्व है जो यूरेनियम अयस्क में ट्रेस मात्रा में होती है। आइसोटोप पोलोनियम -210 कृत्रिम रूप से तैयार किया गया है और उपग्रहों में हल्के ऊर्जा स्रोत के रूप में उपयोग किया जाता है और कुछ उद्योगों में स्थैतिक बिजली को खत्म करने के लिए। प्रतीक: पो; परमाणु संख्या: 84; सबसे स्थिर आइसोटोप का आधा जीवन, 20 9 पीओ: 103 वर्ष; परिमाण: -2, 0, 2, 4 या 6; रिश्तेदार घनत्व: 9.32; पिघलने: 254 डिग्री सेल्सियस; उबलते पीटी: 9 62 डिग्री सेल्सियस
