Dysprosium

Dy

INTRODUCTION

Dysprosium is a silvery, metallic element with an atomic number of 66. It is one of the rare earth elements in the lanthanide series. It usually occurs as the white oxide dysprosia, with erbium and holmium, which are also rare earth elements.

Its name comes from the Greek word dysprositos, 'hard to obtain,' because the element is very difficult to isolate from it's ore.
