| Compare Ionic and Covalent Compounds |
|
Definition
Ionic – metals and non metals, electrons are transferred, solid at room temperature, high melting point, no odour, dissolves in water, conducts electricity in a solution
Covalent – non-metals, shared
electrons, liquid or gas at room temperature, low melting point, have an odour, do not dissolve in water, do not conduct electricity in a solution |

Definition
Telophase - The nuclear membrane forms and gets ready for division
Interphase - The growth and development of the cell
Prophase - The chromatids pair up; nuclear membrane dissolves & centrioles & spindle fibers go to opposite ends.
Anaphase - The chromosones separate by the spindle fibres pulling them apart.
Metaphase - The paired chromatids (chromosomes) line up in the center of the cell. |
