Yttrium-90 (Z= 39, N=51) decays to Zirconium-90 (Z=40, N=50) by emission of a beta particle (Neutron - > Proton + beta minus). Zirconium-90 is stable.
Yttrium has five electron shells.

Yttrium is frequently present in lanthanoids minerals. Now yttrium is considered a transition metal, not a lanthanoid.
