Despite the name #RareEarthElements, these critical metals are actually fairly abundant. In fact, Cerium, which is used in many industrial processes, is more abundant than copper! #IYPT2019
350th anniversary of the discovery of the element #phosphorus and 150 years from invention of periodic table of chemical elements ⚗ #IYPT2019. Based on #LUCAS, we develop the map of topsoil phosphorous(mg Kg-1). High values in West Europe. More info &data https://t.co/I7fcESc6UN
One night in 1669, a German physician heated a mixture of sand, charcoal, and urine in an effort to discover the Philosopher's Stone. He found something else instead. #IYPT2019 #Distillations https://t.co/8EGikj1dBg
I don't know about you, but this periodic table always makes me feel a little wibbly-wobbly timey-wimey. But you don't have to be #InTheTardis to see it! Just visit the #OthmerLibrary digital collection. #IYPT2019 https://t.co/DgpDYdoZ19
Here's the Ytterbium #elementsets samples. Soft enough to chop up with bolt cutters, which generated a faint burning smell (all f-block elements oxidise easily). Will be interesting to see how long the samples keep their lovely golden colour. #OzChem #IYPT2019 @ChemistryMonash
Today is the birthday of Dr Dmitri #Mendeleev, who discovered the periodic law of chemical elements!
今日は元素の #周期律 を発見した #メンデレーエフ さんの誕生日です!

What do you think is the element with the largest atomic number in the PDB?
