रेडियम NOUN
- एक मूलद्रव्य धातु जिसका पता वैज्ञानिकों को हाल में ही लगा है । विशेष—यह धातु अत्यंत विलक्षण और अतीव वहुमूल्य है । इसे शक्ति का संचित रूप ही समझना चाहिए । यह उज्वल प्रकाश- मय होती है । इसके मिलने से परमाणु संबंधी सिद्धांत में बहुत परिवर्तन हुआ है । पहले वैज्ञानिक परमाणु को अयौगिक मूल- द्रव्य मानते थे । पर अब यह पता लगा है कि परमाणु भी अत्यंत सूक्ष्म विद्युत्कणों की समष्टि हैं । यह 'कैन्सर' जैसे दुःसाध्य रोग तथा धातु रोग की चिकित्सा के काम में भी आती है ।
Description
रेडियम एक रासायनिक तत्त्व है।
Radium is a chemical element; it has symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1,600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence.
