Content Standards being covered:

Use the periodic table as a model to predict the relative properties of elements based on patterns of electrons in the outermost energy level of atoms. (HS PS1-1)

Student understands how the periodic table is organized, how that organization can be used to determine an elements properties and trends of properties on the periodic table.
86. Group 1A (Column 1) are called Alkali Metals, Group 2A (Column 2) are called Alkaline Earth Metals, Group 6A (Column 16) are called Chalcogens, Group 7A (Column 17) are called Halogens, Group 8A (Column 18) are called the Noble Gases or Inert Gases, Groups 1B-8B (Columns 3-12) are called the Transition Metals, Elements #57-71 are called the Lanthanide Series and Elements #89-103 are called the Actinide Series
87. Alkali metals are highly reactive with water and reactivity increases down the group
88. Halogens are mainly gases and are highly reactive. Their reactivity increases as you move up the group
89. Noble gases are unreactive because they have a full outer shell/ energy level

Habits of Mind/Life skills being covered:

Thinking Flexibly

Journal Entry:

Sketch a periodic table and then draw the reactivity trends for elements on each side of the table. What two elements on the periodic table are most reactive?
