First Superheavy Element Found In Nature第一超重元素在自然界存在的
The first naturally occurring superheavy element has been found.第一個自然發生的超重元素已經找到。 An international team of scientists found several nuclei of unbibium in a sample of the naturally occurring heavy metal thorium.一個國際科學家小組發現了原子核的unbibium在抽樣調查的自然發生的重金屬釷。 Unbibium has an atomic number of 122 and an atomic weight of 292. Unbibium了原子序數122和原子重量的292 。 In general, very heavy elements tend to be unstable but scientists have long predicted that even heavier nuclei would be stable.總體而言，非常重元素往往是不穩定的，但是科學家們很早就預測，即使是較重的原子核將保持穩定。 The group that found unbibium in thorium say it has a half life in excess of 100 million years and an abundance of about 10^(-12) relative to thorium, which itself is about as abundant as lead.該小組發現，在unbibium釷說，它的半衰期超過1.0億年和豐富的大約10 ^ （ -12 ）相對釷，這本身就是豐富的鉛。
