Let’s Begin…

The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about calcium. Professor Poliakoff thinks calcium is a very British element.

“Cave of the Crystals” or “Giant Crystal Cave” is a cave in Naica, Mexico, only discovered in 2000 by miners. Within this cave, spectacular selenite crystals (CaSO4·2 H2O) have been formed up to 12 m length, 4m in diameter and weighing 55 tonnes!
