Lanthanum and lutetium: lantanides group Actinium and lawrentium: actinides group
Is lutetium radioactive?
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.
What is the longest period in the periodic table?
6th and 7th period are the longest period of the perodic table
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.
What group is Lutetium in on the periodic table?
Lutetium is classified under Group 3, an element under Lanthanides.
