| Metals | Generally Shiny, solid at room temperature except Mercury which is a liquid, good conductors of heat and electricity, malleable, ductile.
🗑

| Group 1 | Alkali Metal. Softer than most other metals, the most reactive, only found as compounds with other elements.
🗑
|

| Group 2 | Alkaline Earth Metals.
Chemically reactive and are not found as often.
🗑
|

| Groups 3-12 | Transitional Metals. They are the most familiar because they occur in nature.
🗑
|
||||
| Non -Metals | Often gases. Poor conductors of heat and electricity. Often react with metals and pick up electrons. Most reactive are Halogens
🗑
|

| Nobel Gases | Group 18, the most stable, react and combine easily with other substances.
🗑
|
||||
| Metalloids | Have properties of both metals and nonmetals
🗑
|

| Stability | Stable elements are unreactive
🗑
|

| Order of Stability | -full outer shell
-full sublevel
-half-full sublevel
-one electron in the outer shell or seven electrons in the outer shell
Note: Atoms react to become more stable than before.
🗑

| Lewis dot diagram | Begin by writing down the element symbol
Write the electron configuration
Each side of the element represents an outer orbital. fill in the dots according to the different orbitals.
