About Me.

A Family Tree researcher for over 30 years and a blogger since 2010, I love to share what I find. This blog has opened up a new way to contact and keep in-touch with both family and friends. It mightn't always be genealogy related and you might not agree with my point of view but I want you to comment, ask questions and look upon this blog as 'friends having a chat'.
Enjoy!

April 29 Y is for Yttrium



                                                           YTTRIUM

Yttrium is a chemical element with the symbol Y and the atomic number 39. It also has an atomic weight of 88.9.  It is used in making phosphors and exposure to it can cause lung disease.  It is a soft silver-metallic classed as a transitional metal in the group 3.  It is also listed as a rare earth mineral. Discovered by Johan Gadolin in 1794, it was  first isolated by  Carle Gustav Mosander in 1840.  Named after Ytterby, a Swedish village, near where it was found.

So now you know as much about Yttrium as I do an interesting and important element of the Periodic Table of Elements.

Bye for now,
Lilian.
