Scientists finally solved a 150-year-old gallium mystery

Scientists at the University of Auckland have discovered that gallium's covalent bonds reappear at high temperatures after melting. This finding challenges long-held assumptions about the metal's atomic structure and explains its unusually low melting point.
Why it matters
Understanding the fundamental properties of gallium is essential for improving its application in semiconductors and modern electronic technologies.
Nearly 150 years after gallium was first discovered and added to the periodic table, scientists at the University of Auckland have uncovered previously unknown details about the metal's atomic structure and behavior.
