Electronegativity Gradient

The difference in Pauling electronegativity (ΔEN) directly dictates chemical bonding nature: ΔEN ≥ 1.7 typically yields ionic bonds with lattice energy stabilization, while ΔEN < 1.7 forms polar or covalent electron sharing.

Ionization Energy Discontinuities

Watch for half-filled (p³, d⁵) and fully-filled (s², d¹⁰, p⁶) subshell quantum stabilities. Elements with symmetric configurations have unexpectedly higher 1st ionization energies than subsequent elements.
