Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Atomic number The number of protons in an atom. Electron configuration
Yttrium is a silvery-metallic transition metal with atomic number 39 and symbol Y. Its electron configuration is [Kr] 4d 1 5s 2, with 3 valence electrons and 2 valency electrons.
Properties. Yttrium is a soft, silver-metallic, lustrous and highly crystalline transition metal in group 3. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium.
Electron Configuration. [Kr] 4d 1 5s 2. Y. Finely divided yttrium is very unstable in air.
Electron configuration of Yttrium is [Kr] 4d1 5s2. Possible oxidation states are +3. Most Common Compounds of Yttrium. An yttrium compound is a chemical compound containing yttrium (element symbol: Y). Among these compounds, yttrium generally has a +3 valence. The solubility properties of yttrium compounds are similar to those of the lanthanides.
