We can calculate a more general bond energy by finding … WebbThird, bond energy (in a covalent bond) is primarily determined by how well the electron orbitals overlap from the two atoms. Greater overlap creates a stronger bond. Effective nuclear charge isn't as major a factor as the overlap. We can determine things like electronegativity or bond polarity with the help of effective nuclear charge however. ship hazmat software
