Bonding
Ionic Evidence for the existence of ions - Physical properties: high mpt and high bpt,
molten and
aqueous samples are conductive whereas solid samples are not, soluble in polar
compounds - Electron density maps show areas with low/ no electron
density between ions - Conductivity of aqueous solutions shown…

a certain degree -Group 1 halides values differ very little, so they are mostly ionic -BeF
2

though, has very different values -Explanation through polarisation:
- Polarisation: distortion of electron cloud
in ion/ molecule by nearby charge - Cations with high charge density (high charge, low
radius) will draw electrons…
