Learning Intentions
You can organize the elements from the periodic table to create a form of organization based on their names and properties.
You can identify the names of the different families on the periodic table.
You can color a periodic table to show the different families, different phases the elements are at room temperature, whether they are metals, metalloids or non metals and which elements are diatomic elements.
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.
81. The periodic table is arranged by increasing atomic number.
83. The period, or row, signifies the number of energy levels that an atom
contains
85. The vertical columns, called groups or families, consist of atoms with the
same number of electrons in the outer energy level and therefore the same
chemical properties.
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
92. Metals are on the left side of the periodic table and non-metals are on the
right. A zigzag line separates the two, and atoms along this line have
properties of both metals and non-metals. They are called metalloids.
100. Seven elements exist as diatomic molecules in pure form- they are Hydrogen
(H2), Oxygen (O2), Nitrogen (N2), Fluorine (F2), Chlorine (Cl2), Bromine (Br2),
and Iodine (I2)
