Types of bonding

Types of bonding. There are three types of bond that can occur between atoms:. an ionic bond occurs between a metal and non-metal atom (e.g. NaCl). a covalent bond occurs between two non-metal atoms (e.g. I 2 , CH 4 ). a metallic bond occurs between atoms in a metal (e.g. Cu).

WHY?

WHY?. Why is water usually a liquid and not a gas? Why does liquid water boil at such a high temperature for such a small molecule? Why does ice float on water? Why do snowflakes have 6 sides? Why is I 2 a solid whereas Cl 2 is a gas? Why are NaCl crystals little cubes?.

Diluting Solutions

Diluting Solutions. You can make a less concentrated solution of a known solution by adding a measured amount of additional solvent to the standard solution. The number of molecules, or moles of solute remains the same before and after the dilution. Side note on formulas for this module.
