The Periodic Table of the Elements
Table 1 and the vocabulary/concepts/labs outline is a review of the work you have done recently in the Properties of
Matter Unit. Use it, along with your journal and warm ups, lab worksheets, class notes, element packet, periodic table, and
other worksheets to prepare for a test on Compounds, Elements, Chemical Reactions and the Periodic Table. Prepare a 3”
X 5” notecard with important information of your choosing. Practice on the questions that follow the table. **You do not
need to memorize the information in the Elements Packet. During the test, you will have access to a periodic table.

Vocabulary:
Key Content
Compounds, such as water, are pure substances.
Compounds are composed of more than one element
combined together.
Compounds, unlike mixtures, do not vary in their
composition.
Compounds have different characteristic properties than
those of elements from which they are composed.
Compounds can be decomposed into their constituent
elements
Compounds can be synthesized from elements.
Elements are pure substances that cannot be broken
down into other substances.
There are more than 100 different types of elements.
Elements can be identified by their characteristic
properties.
Many elements are poisonous or hazardous to handle.
In nature, most elements are found as compounds,
combined with other elements.
The way elements are used is determined by their
properties.
Elements can be grouped according to their
characteristic properties.
The periodic table classifies elements according to their
properties.
Elements can be categorized into two major groups: the
metals and non-metals.
Metals are a group of elements with similar properties,
including a shiny appearance and the ability to conduct
electricity and heat.
Metals have similar, but not uniform, properties
(for example, only some metals are magnetic; some
metals are hard, and others are soft).
Metals can form compounds with nonmetals.
Metals vary in their reactivity and can be arranged in a
reactive series.
Rusting is a chemical reaction.
The mass of the reactants in a chemical reaction is the
same as the mass of the products.
The fact that mass can be conserved can only be
measured in a closed system.
Conservation of mass applies to all changes involving
matter and can be defined as the law of conservation of
mass.
Related Skills
Use electrolysis to split compounds.
Test for hydrogen and oxygen.
Compare the characteristic properties of compounds
with those of the elements from which they are
composed.
Describe elements.
Collate information on the characteristic properties of
elements.
Recognize groups with similar properties.
Identify these approximate groups in the periodic table.
Identify common elements you have encountered.
Suggest possible uses of the elements you have
encountered.
Identify metals and nonmetals by their properties.
Na + Cl  NaCl
Sodium + Chlorine  Sodium Chloride
Observe metals reacting and then use this information
to list the order of their reactivity.
Do an experiment to determine the conservation of
mass in a chemical reaction.
Recognize an open and closed experimental system.
Apply conservation of mass of phase change,
dissolving, and chemical reactions.
Define the law of conservation of mass.

______ 7. These metals are shiny, metallic and good conductors of heat and electricity.
Metals vs. Non-Metals:
12. List as many characteristic properties as you can think of that metal elements have in common, be
specific. (list at least 6)
13. List as many characteristic properties as you can think of that non-metal elements have in common, be
specific. (list at least 6)

15. Find Fluorine on your periodic table then answer the following.
a. Group number? ______
d. Atomic Number? ______
b. Period number? ______
e. Atomic Mass? ______
c. Family Name?
_______________________
f. How many protons? ______
h. Draw a picture of the atom
g. How many electrons? _____
16. Explain the difference between an element and a compound, give an example of each.
17. A compound is made of two or more elements joined together. The subscript (small number) written
after each element symbol represents the number of atoms that are present in each molecule of that
compound. If no number is written after the element symbol then you can assume that only one atom is
needed. List the names of the elements in each of the following compounds and the number of atoms
present in each molecule.
a. Water: H2O ____________________________________________________________________
b. Table salt: NaCl ________________________________________________________________
c. Baking soda: NaHCO3 ___________________________________________________________
d. Table sugar: C12H22O11 ________________________________________________________
