Cesium was the first element to be discovered using a spectroscope. Bunsen and Kirchhoff named cesium after the blue lines they observed in its spectrum. Caesium (cesium) is a Latin word that means "sky blue".  ]]> 2016-11-01 18:18:43 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/134586329 vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/136495460 2016-11-09 17:45:03 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/136495460 Melting point: vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/136497077  1240°F (28.44°C) ]]> 2016-11-09 17:48:14 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/136497077 vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/137266084 2016-11-14 04:48:48 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/137266084 Boiling point vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/137266608 83.19°F (28.44°C)]]> 2016-11-14 04:57:57 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/137266608 Density vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/137266960 1.93 grams per cubic centimeter]]> 2016-11-14 05:04:22 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/137266960 Abundance in earth's crust vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/137267656 45th most abundant in the earth's crust]]> 2016-11-14 05:16:42 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/137267656 Isotopes vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/137268510 Cesium has 40 known isotopes but only 133Cs is stable]]> 2016-11-14 05:34:18 UTC https://padlet.com/vega1510/nwy40risxw3o/wish/137268510 Uses vega1510 https://padlet.com/vega1510/nwy40risxw3o/wish/137268885 - Drilling fluid
