Nature favors a more stable arrangement and leads to bonding between atoms. Docsity.com Covalent Bond or Ionic Bond? • The type of bond that takes place depends on the atoms electronegativity (the measure of an atom’s ability to attract electrons). It is determined by the difference between the two (pg. 161 – electronegativity periodic table). Docsity.com Covalent or Ionic? • Nonpolar Covalent – Difference between 0.0 and 0.3 • Polar Covalent – Difference between 0.31 and 1.7 • Ionic – Difference between 1.71 and 3.3 Docsity.com Examples • What type of bond exists between Sulfur and: – Hydrogen? – Cesium? – Chlorine?
