anyhting about dysprosium....theres nothing on wikipedia, about what i need?

Question

i said theres nothing on wikipedia, ok.....

who found it, its uses, how common is it, is it dangerous?

Answer 1

Dysprosium (Dy) is a Lanthanide and belongs to the elements where the energy levels of the 4f sub-shell is lower than the 5d and the 6p energy levels. But in Dy it is the 5d sub-shell that accepts the electron. This would make me think that its chemistry was more similar to Lanthanum(La) and Lutetium(Lu). Perhaps a Lanthanide chemist will enlighten us. You could try looking up their properties on an 'Atomic Energy' web site as their nuclear chemistry will be different from their electronic chemistry and their reactions can be traced using their radioactive isotopes.
It is said to be chemically toxic.

The name, Dysprosium, is Greek for 'difficult to obtain"
Discovered by Boisbaudran 1886.
Two extra ines could be seen in spectroscopy of purified Holmium ores which pointed to the presence of an unknown element.

I would assume that its chemistry is parallel to that of Holmium and the book gives no details of the separation of the two metals.
