Transcript Coloring the Periodic Table

Warm-up February 7
 1. Identify the following elements as a metal, non-metal,
or a metalloid.
 Hydrogen
 Sodium
 Helium
Copper
Arsenic
Boron
2. In your own words tell me how you would describe to a
third grader where the metals, non-metals, and metalloids
are located on the periodic table.
10 NEED TO KNOWQUIZ NEXT FRIDAY!!
 water (H2O)
 household bleach
 carbon dioxide (CO2) (NaClO)
 sucrose (C12H22O11)  hydrochloric acid (HCl)
 table salt (NaCl)
 ammonia (NH3)
 oxygen (O2)
 baking soda (NaHCO3)
 vinegar 5% solution
(HC2H3O2)
LETS REFLECT ON OUR
BENCHMARK
 Good News or bad news?
 Problems you had?
 What can we do to fix this?
Get out your Periodic Tables!! 
Families on the Periodic Table
 Elements on the periodic table can be grouped into
families bases on their chemical properties.
 Each family has a specific name to differentiate it
from the other families in the periodic table.
 Elements in each family
react differently with
other elements.
ALKALI METALS
Group 1
 Hydrogen is not a member, it is
a non-metal
 1 electron in the outer shell
 Soft and silvery metals
 Very reactive, esp. with water
 Conduct electricity

ALKALINE EARTH METALS
Group 2
 2 electrons in the
outer shell
 White and
malleable
 Reactive, but less
than Alkali metals
 Conduct electricity
Feb. 10, 2013
 Use your Periodic table to name these elements:
 Group 14, Period 2
 Group 11, period 4
 Group 2, Period 2
 Group 17, Period 3
 Group 18, Period 1
A trick to remember
 Friday we talked about reactivity and charges (HONC)
 If that confused you maybe this will help
 The elements on the periodic table have to add up to 18
to be stable (Use group numbers).
 Group 18 is already stable  Doesn’t need or want
anyone
 Ex. NaCl= 1+17= 18 
 H2O= 1+1+16= 18 
Today
 Pop-quiz
 Review Benchmark
 Add to periodic table families.
 Reminder: Quiz Friday on 10 need to know!!
(You wrote these on Friday)
Pop Quiz
 You will draw a number. That is the number you have
to solve for. Solve for each number below and turn in
with your slip and sheet. You may use a periodic table.
 1. Give me the Element Symbol
 2. Give me the Element Name
 3. Atomic Number
 4. Atomic Mass
 5. # of Protons
 6. # of Electrons
 7. # Neutrons
Review Benchmark
 Scores on Board
 Scores individually
 Go over most missed first
 Congrats:
 3 questions no one missed in our class
 Only 3 questions were less than 70% of you got right
 Mastery on ecosystems 
 The school average was a 55%
 The county average so far is a 56%
TRANSITION METALS
Groups in the middle
 Good conductors of
heat and electricity.
 Some are used for
jewelry.
 The transition metals
are able to put up to 32
electrons in their
second to last shell.
 Can bond with many
elements in a variety of
shapes.
BORON FAMILY
Group 3
 3 electrons in the
outer shell
 Most are metals
 Boron is a
metalloid
CARBON FAMILY
Group 4
 4 electrons in the
outer shell
 Contains metals,
metalloids, and a
non-metal Carbon
(C)
NITROGEN FAMILY
Group 5
 5 electrons in the
outer shell
 Can share electrons
to form compounds
 Contains metals,
metalloids, and
non-metals
OXYGEN FAMILY
Group 6
 6 electrons in the
outer shell
 Contains metals,
metalloids, and
non-metals
 Reactive
Halogens
Group 7
 7 electrons in the
outer shell
 All are non-metals
 Very reactive are
often bonded with
elements from
Group 1
Noble Gases
Group 8
 Exist as gases
 Non-metals
 8 electrons in the
outer shell = Full
 Not reactive with
other elements
Rare Earth Metals
 Some are
Radioactive
 The rare
earths are
silver, silverywhite, or gray
metals.
 Conduct
electricity
