Ittrium silih tunggil datu kimia antuk simbol Y miwah wilangan atom 39. Punika logam transisi mawarna logam masawang pérak antuk sacara kimiawi sekadi lantanida miwah ketah kaklasifikasiyang dados "datu tanah langka".^[5] Itrium ketah katemuin ring campuhan sareng datu lantanida ring datu tanah langka, miwah tan naénin katemuin ring palemahan dados datu bébas. ⁸⁹Y punika wantah asiki isotop sané tegtteg, miwah dados asiki isotop sané katemuin ring kerak gumi.
