2. Identify, measure, and use a variety of physical and
chemical properties (electrical conductivity, chemical reactivity).
4. Describe trends in properties (ionization energy or
reactivity as a function of location on the periodic table).
8. Make predictions about elements using the periodic
table (number of valence electrons, metallic character, reactivity, conductivity,
type of bond between elements).
Specifications:
metals, and nonmetals
properties of bonding based upon location on the periodic
table include orbital diagrams and electron configuration of representative
elements, Lewis Structures of single center molecules and polyatomic ions,
polarity.

| OBJECTIVES |
|
OBJECTIVE (SWBAT):
Given the name of an element, write its correct symbol;
from the symbol, write the correct name.
Explain how the elements are organized in a periodic
table.
Understand what the periodic table of elements represents;
use the periodic table to identify the group and the period of an element.
Identify the characteristic of representative groups.
Identify three broad classes of elements.
Use the periodic table to determine whether an element
is a metal, nonmetal, or metalloid.
Describe the information in a periodic table.
Classify elements based on physical and chemical properties.
Distinguish representative elements and transition metals.
BIG IDEAS:
Elements are pure substances that cannot be broken down
by chemical means.
Elements are represented by chemical symbols.
The periodic table is an arrangement of all known elements,
in groups of similar properties and rows of increasing atomic number.
ESSENTIAL QUESTIONS (SWBATA):
What are elements?
How are elements represented?
How is the periodic table organized?
What are the three broad categories of elements?
What type of information can be displayed in a periodic
table?
What is the underlying cause for observed periodic trends? |
