Bonds
| Term | Definition |
|---|---|
| Strong bond | Strong chemical bonds hold atoms together inside molecules. |
| Weak bond | Weak bonds hold separate molecules or parts of molecules close to each other. |
| Covalent bond | A covalent bond is a chemical link where two atoms share one or more pairs of electrons. |
| Polar covalent bond | A polar covalent bond is a chemical link where two atoms share electrons unequally because one atom has a higher electronegativity than the other. |
| Metallic bond | A metallic bond is the strong electrostatic attraction between positive metal ions and a shared "sea" of free-moving, delocalized electrons, while an alloy is a mixture of two or more elements where at least one is a metal |
| Ionic bond | An ionic bond is a chemical link formed through the electrostatic attraction between oppositely charged ions after one atom transfers electrons to another. |
