In our new video about Erbium, The Professor explains why it is perhaps the most important element for websites like YouTube. More links in description below ↓↓↓ Support Periodic Videos...
========== Lovely!I’ve just realised that erbium is the most
crucial element for the internetof all the elements on the periodic table,
and so I want to take youacross to materials engineering where we can
see a demonstration whichwill explain to you why it’s so important,
and why without erbium manyof you couldn’t be watching this video.Erbium is another lanthanide metal. It’s
soft, silvery, quite malleable,very reactive towards oxygen and water and,
