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.

钇（Yttrium）是一种银白色金属，元素符号为Y，它是第一个被发现的稀土金属元素，有延展性。 钇在自然中并不以电离态存在，而是和镧系元素共同伴生于稀土矿物中，是重稀土元素中地壳丰度最高的元素。
