The periodic table is a chart that shows how chemical elements are related to one another. The actinides get their name from element 89, actinium, which is sometimes considered the first member of the family. Plutonium is also called a transuranium element. The term transuranium means "beyond...
No need to do the calculations: Not very much neptunium at all would be left! Perhaps, too little to even find in the Earth's crust. So what does this example suggest about other transuranium elements, such as plutonium (number 94) and americium (number 95)? All of these elements ...
Any of a series of chemically similar metallic elements with atomic numbers ranging from 89 (actinium) to 103 (lawrencium). All of these elements are radioactive, and two of the elements, uranium and plutonium, are used to generate nuclear energy. SeePeriodic Table. ...

其中放射性極高的元素鈈(Plutonium) 更需要 240,000 年時間, 才能讓幅射下降至安全水平。 legco.gov.hk legco.gov.hk Apart from radon, may I know whether there are otherradioactive elementsinconstruction materials that are also harmful to human health?
