Ytterbium
Chemistry; General chemistry
Element 70, atomic weight 173.04, a very rare, malleable metal used in special alloys for X-ray sources.
Decomposition
Chemistry; General chemistry
A reaction in which a compound is broken down into simpler compounds or elements. Compounds sometimes decompose if heated strongly or if subjected to a strong electric current (electrolysis ).
Low spin complex
Chemistry; General chemistry
A metal-ligand complex with fewer unpaired electrons than the uncomplexed metal ion. When a strong ligand complexes the metal ion, the crystal field splitting is large and some electrons pair ...
Spin pair
Chemistry; General chemistry
Two electrons with opposite spins , usually occupying the same orbital.
Bidentate
Chemistry; General chemistry
A ligand that has two "teeth" or atoms that coordinate directly to the central atom in a complex. For example, 1,10-phenanthroline is a bidentate ligand of iron.
