| hydrogen bond | The attraction between a positively charged H end of a molecule to a negatively charged end (usually O or N) of a molecule.
🗑
|
||||
| Ionic bond | The attraction of oppositely charged ions, a cation and an anion. One atom gains electrons and one loses electrons
🗑

🗑
|
||||
| Colloid properties | A mixture that will not settle out. The size of the solute particles are large enough that they disperse light and the mixture appears opaque (milk).
