They are manmade and located below the lanthanides on the periodic table.]]> 2019-10-21 17:35:28 UTC https://padlet.com/wipe570/ipjgq2r7gji/wish/400463388 wipe570 https://padlet.com/wipe570/ipjgq2r7gji/wish/400465348 2019-10-21 17:38:23 UTC https://padlet.com/wipe570/ipjgq2r7gji/wish/400465348 wipe570 https://padlet.com/wipe570/ipjgq2r7gji/wish/401008420 2019-10-22 17:11:20 UTC https://padlet.com/wipe570/ipjgq2r7gji/wish/401008420 wipe570 https://padlet.com/wipe570/ipjgq2r7gji/wish/401011917 Actinides are radioactive and have, with the exception of one, several crystalline phases. They can also lose multiple electrons to form different ions. They are also very heavy and man made.]]> 2019-10-22 17:15:47 UTC https://padlet.com/wipe570/ipjgq2r7gji/wish/401011917 wipe570 https://padlet.com/wipe570/ipjgq2r7gji/wish/401012659 Actinides are very similar to lanthanides. They are also highly unstable and some only exist for a few milliseconds.]]> 2019-10-22 17:16:54 UTC https://padlet.com/wipe570/ipjgq2r7gji/wish/401012659
