Bond Lengths
Nuclear separation distance leads to a stable molecule
Attractive interactions are maximised but equal to repulsive interactions
Bond Trends
Small atoms= shorter bonds
More electrons present in a bond, shorter the bond
Bigger the electronegativity difference with bonded atoms, shorter the
bond
Bond Energy Trends
Bonds become shorter as energy increases
More electrons present increases the bond energy
Bigger the difference in electronegativity in bonded atoms, bigger the
bond energy
Ionic Bonding
Lattices
Formed from ionic compounds
Contains strong electrostatic forces between ions
