Then Actinides at 89,This is the Periodic Table,Noble gas is stable.Halogens and Alkali react aggressively.Each period will see new outer shells.While electrons are to the right.Actinium,Thorium,Protactinium,Uranium,Neptunium,Plutonium,Americium,Curium,Berkelium,Californium,Einsteinium,...

更新1: I want to clearify one thing Co((OH)2Co(NH3)4)3 is the formula of the ion it has 6 hydroxo- and 12 ammine- 更新2: and it is given that it is a positively charge ion does it help?0. no it's probably not octet rule. it should be 18-e...

Radioactive contamination, resulting from 20th century activities in atomic physics, such as nuclear power generation and nuclear weapons research, manufacture and deployment. (See alpha emitters and actinides in the environment.)Noise pollution, which encompasses roadway noise, aircraft noise,...

Thallium and Lead then Bismuth for your tummy Polonium, Astatine would not be yummy Radon, Francium will last a little time Radium then Actinides at 89 REPEAT CHORUS Actinium, Thorium, Protactinium Uranium, Neptunium, Plutonium Americium, Curium, Berkelium Californium, Einsteinium, ...
