They are soft, mallable, shiny medals that have high conductivity. Often, they are mixed with other common metals to make alloys which are mixtures of elements with at least one other element.]]> 2019-06-11 15:42:10 UTC https://padlet.com/rhmc357/f4v9tzy4kby/wish/366975869 bedo353 https://padlet.com/rhmc357/f4v9tzy4kby/wish/366976530 2019-06-11 15:45:13 UTC https://padlet.com/rhmc357/f4v9tzy4kby/wish/366976530 rhmc357 https://padlet.com/rhmc357/f4v9tzy4kby/wish/366977266 They are loceted in the row below the lanthanides. Only a few of these elements occur naturally on earth. Many are created artificially in laboratories. Many are used to produce energy. The nuclei of these elements are unstable so many of them only last for a fraction of a second after they are made]]> 2019-06-11 15:48:11 UTC https://padlet.com/rhmc357/f4v9tzy4kby/wish/366977266 bedo353 https://padlet.com/rhmc357/f4v9tzy4kby/wish/366977673 Thorium, Neptunium, Americium, Californium, and Mendelevium ]]> 2019-06-11 15:49:47 UTC https://padlet.com/rhmc357/f4v9tzy4kby/wish/366977673 bedo353 https://padlet.com/rhmc357/f4v9tzy4kby/wish/366978891 Cerium, Promethium, Gadolinium, Dysprosium, and Ytterbium]]> 2019-06-11 15:53:52 UTC https://padlet.com/rhmc357/f4v9tzy4kby/wish/366978891 rhmc357 https://padlet.com/rhmc357/f4v9tzy4kby/wish/366980636 ~Many different lanthanides are found together in nature. They are difficult to separate because they share very similar properties
~Neodymium is used in manufacturing the tiny speakers inside headphones
~Uranium is used to produce energy in nuclear power plants
~Curiumis used as a source of high-energy particles that heat and provide power for certain scientific equipment aboard the mars exploration rover]]> 2019-06-11 16:01:41 UTC https://padlet.com/rhmc357/f4v9tzy4kby/wish/366980636 bedo353 https://padlet.com/rhmc357/f4v9tzy4kby/wish/366983059 ~Placed below the  main part of the periodic table. 
~Lanthanides  are soft, malleable, and shiny they have a high conductivity. 
~Actinides have very unstable nuclei 
~only some Actinides are produced naturally others are manufactured in laboratories
