For most practical purposes, lutetium can be regarded as stable, though it is slightly radioactive. 97.41% of lutetium found in nature is stable, and 2.59% is of an isotope with a half life of 37,800,000,000 years. Like all other elements, lutetium has synthetic radioactive isotopes.

What is the Bohr model for lutetium?
If you think to the electron configuration of lutetium this is: [Xe]4f14.5d1.6s2.
Which really belong to group iii - lanthanum and actinium or lutetium and lawrencium?
Lanthanum and actinium belong to group III, while lutetium and lawrencium do not. Lutetium and lawrencium belong to the lanthanide and actinide series, respectively.
What are lutetium chemical properties?
Lutetium's compounds always contain the element in the oxidation state +3. Lutetium metal is slightly unstable in air at standard conditions, but it burns readily at 150 °C to form lutetium oxide. In reaction with water it is slow when cold and fast when hot; lutetium hydroxide is formed in the reaction. All halide salts (except fluoride) are soluble in water. Lutetium dissolves readily in weak acids and dilute sulfuric acid to form solutions containing the colorless lutetium ions, which exist as a [Lu(H2O)9]3+ complex (nonate, hydrate) ions.
Is lutetium synthetic or natural?
natiural
What is a good slogan for lutetium element?
