              Actinium: the essentials

              Actinium atoms have 89 electrons and the shell structure is 2.8.18.32.18.9.2. The ground state electronic configuration of neutral actinium is [Rn].6d1.7s2 and the term symbol of actinium is 2D3/2.

              Actinium: description  

              网络斗地主下载Actinium is dangerously radioactive. The chemical behaviour of actinium is similar to that of the rare earths, particularly lanthanum. It is found naturally in uranium ores and actinium is 150 times more radioactive than radium.
