the properties of elements that had
not yet been discovered?
4) What information about an element
is given in each square of the
periodic table?
1) Melting point, .density, color, atomic
mass, and the number of chemical
bonds it could form.
2) When he arranged the elements in
order of increasing atomic mass
3) He noticed a repeating pattern of the
elements
4) Atomic number, chemical symbol,
name, atomic mass
5) From the information in each square,
what do you know about the
structure of the element?
6) What are the rows of the periodic
table called?
7) How do the properties of the metals
in a period change from left to right?
8) What are the columns in the periodic
table called?
5) The number of protons and electrons
and the average number of neutrons
6) periods
7) From highly reactive to very
unreactive
8) groups. By looking at an element’s
periodic group, you can find other
elements with similar properties
Read p. 609-617
1)Objective: I will learn about the
different properties elements may have.
2) Essential Question: Can I evaluate
the significance of the different
properties of elements
3) Warm-up: How is the modern day
periodic table different than the one
created by Dmitri Mendeleev?
4) Vocabulary: ductility, malleability,
conductivity, reactivity, magnetism
1) Malleability= the ability of an element to be
rolled into thin sheets.
2) ductility= the ability of an element to be
stretched into wire
3) conductivity= the ability of an element to
transfer heat or electricity to another object.
4) reactivity= the ease and speed with which an
element combines with other substances
5) magnetism= the ability of an element to attract
other materials.

identify the use of metals in everyday
life?
3) Warm-up: Answer the Math
Analyzing Data questions on page 621.
4) Vocabulary: corrosion, alloy,
semiconductor, periodic group

metal. (Example: alloy rims on cars)
3) Semiconductor= An element that conducts current under
certain conditions. Example: the use of silicon in
cellphones and other electronics.
4) Periodic group= the horizontal rows of the periodic table,
arranged based on their similar properties. (example: by
looking at an element’s periodic group, you can find other
elements with similar properties)

Tips for Success on Today’s Vocabulary Quiz
1) Think of each statement in the way it would be
said by someone.
2) Think of the hints (underlined words) in the
statement that give away the vocabulary word.
3) Read all of each statement first and match the
statement with the word that best fits.
4) I believe in you. I know you will do well.
Believe in yourself also and you will be amazed.
Congratulations! You are about to have the grand
opening for your first business. You have decided to
open up a store of metals. It’s time to get to work so
you can load the store full of customers for the grand
opening. Think of the types of metals you will sell
and what they might be useful for. You may refer to
the list of metal objects you found in the scavenger
hunt yesterday.
Steps for creating the store of metals
1) Identify 5 metals your store will sell.
2) Draw illustrations depicting what the
metals you sell may be used for.
3) Come up with a name for your store
of metals. Create a propaganda
slogan to market your store to the
public
4) Prepare a commercial to present to
the class advertising your store.
