Chemical Bonds
Types of Chemical Bonds table 2.3
| Term | Definition |
|---|---|
| Ionic Bond | Relatively weak attraction between an atom and a cation. easily disrupted in water, as when alt dissolves. |
| Covalent Bond | Sharing of one or more pairs of electrons between nuclei. |
| Single Covalent Bond | Sharing of one electron pair. |
| Double covalent Bond | Sharing of two electron pairs. Often occurs between carbon atoms, between carbon and oxygen and between carbon and nitrogen. |
| Nonpolar covalent Bond | Covalent bond in which electrons are equally attracted to both nuclei. May be single or double. Strongest type of chemical bond. |
| Polar covalent | Covalent bond in which electrons are more attracted to one nucleus than to the other, resulting in slightly positive and negative region in one molecule. May be single or double. |
| Hydrogen Bond | Weak attraction between polarized molecule or between polarized regions of the same molecule. Important in the three-dimensional folding and coiling of large molecule. Easily disrupted by temperature and pH changes. |
| Van der Waals Force | Weak, brief attraction due to random disturbances in the electron clouds of adjacent atoms. Weakest of all bonds. |
