Source sentences:
text: If astatine instead has an (unmetallic) orthorhombic structure, its unit cell volume can be indicatively extrapolated using the cube of its predicted covalent atomic radius of 1.5 Å.
text: Astatine might instead form a metallic structure either due to relativistic effects like in Po, or all by itself due to Goldhammer-Herzfeld criterion ratio being >=1, in which case hello metallic appearance.
