← ScienceWhich risk increases substantially when calcium fluoride (CaF2) is heated beyond its melting point?
A)Increased electrical conductivity develops acutely✓
B)Neutron emission from the compound rises
C)Covalent bond formation in molten salt
D)Sublimation rate of the species grows
💡 Explanation
Increased electrical conductivity arises because, above the melting point, ionic dissociation leads to freely moving Ca2+ and F- ions; therefore, ion mobility produces conductivity rather than only solid diffusion, causing the increase compared to non-ionic scenarios.
