How can you determine is a substance is an acid?
If the substance is mixed with cabbage water, if it is an acid, the mixture should turn pink.

Draw a Bohr Model for Magnesium.
- 3 shells - 3rd horizontal row
- 12 toatle electrons

How does any of the alkali metals react to water?
When the alkali metals are introduced to water, the bounce around the water, catch on fire, or explode. All of them produce hydrogen when they are introduced to water.
200
How can you determine if a substance is a base?
When the substance is mixed with cabbage water, if the mixture turns blue, the substance is a base.

Draw a Bohr Model for Potassium.
- 4 shells - 4th horizontal row
- 19 toatle electrons
- 1 valence electron in its outer shell - 1st vertical tall column
300
Draw the Lewis Dot Structure for Carbon.

What do the alkali metals do when they are cut?
Corrosion occurs and they turn a different color.
