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.

Direct parent isotope is: 88 Zr. Nuclear isomers or excited states with the activation energy in keV related to the ground state. The following table shows the atomic nuclei that are isotonic (same neutron number N = 49) and isobaric (same nucleon number A = 88) with Yttrium-88.
