A rough guideline:
• ions will form if the difference in electronegativity between interacting atoms is 1.9 or greater
• example: sodium (EN 0.9) and fluorine (EN 4.0)
• about 1000 new ones are identified each day!
C is a small atom
• it forms single, double, and triple bonds • it is intermediate in electronegativity (2.5) • it forms strong bonds with C, H, O, N, and some metals
Although all covalent bonds involve sharing of electrons, they differ widely in the degree of sharing
We divide covalent bonds into
• nonpolar covalent bonds • polar covalent bonds
