Jedrzej Sniadecki was testing out different metals and supposedly discovered ruthenium but he couldn't finish his research, and neither could  Gottfried Osann, which led Karl to be the one who was named the discoverer of ruthenium.]]> 2017-10-30 17:10:21 UTC https://padlet.com/emmahallaz/pgt5vd5msox2/wish/201833168 emmahallaz https://padlet.com/emmahallaz/pgt5vd5msox2/wish/201839304

It is the 74th most abundant element on Earth making it very rare. It can be used for ammonia, acid formulas, etc. It is also used for chip resistors to protect them. This element is used in an everyday life mainly for scientists and their research.]]> 2017-10-31 17:08:19 UTC https://padlet.com/emmahallaz/pgt5vd5msox2/wish/202243637
