Curium is a hard, dense silvery metal with a relatively high melting point and boiling point for an actinide. Whereas it is [[paramagnetism|paramagnetic]] at [[Standard conditions for temperature and pressure|ambient conditions]], it becomes [[antiferromagnetism|antiferromagnetic]] upon cooling, and other magnetic transitions are also observed for many curium compounds. In compounds, curium usually exhibits [[valence (chemistry)|valence]] +3 and sometimes +4, and the +3 valence is predominant in solutions. Curium readily oxidizes, and its oxides are a dominant form of this element. It forms strongly [[fluorescence|fluorescent]] complexes with various organic compounds, but there is no evidence of its incorporation into [[bacteria]] and [[archaea]]. When introduced into human body, curium accumulates in the bones, lungs and liver where it promotes [[cancer]].
