Get Organized, Baby! - Task 2
It’s All Elemental v3 Worksheet
Click on the first website listed.
1. Why are the elements placed in specific places on the Periodic Table?
Because of the way they look and act
2. Periods are rows that run from left to right.
3. Elements in the same period have the same number of electron shells(orbits).
4. Every element in the first period has 1 shell for its electrons. Every element
in the second period has 2shells for its electrons. See the pattern?
5. Groups are columns that run from top to bottom.
6. The elements of a group have the same number of electrons in their
outer(valence) shell.
7. Every element in group one has 1 electron in its outer shell. Every element in
group two has 2 electrons in its outer shell.
8. Hydrogen is special because it can act like two groups, 1 and 7.
9. Hydrogen sometimes is missing an electron and sometimes it has an extra
electron.
10. Although helium has only 2 electrons in its outer shell, it is grouped with
elements that have 8.
11. The gray elements on this table are called transition elements. They each
have two electrons in their outer shell.
Task 3
**As a class you will color code your periodic table. Number the groups 118 and periods 1-7, 6 and 7 on your periodic table. Ask your teacher if you
need help before you do this.

12. Click on Alkali Metals (left bar) and answer the following questions.
a. What is the group number? 1
b. Are these metals reactive? yes
c. Do these metals occur freely in nature? no
d. How many electrons are in their outer shell? 1
e. What are the three characteristics of ALL metals? Malleable, ductile, good
conductors of heat and electricity
f. Are these metals soft or hard? soft
g. Name the two most reactive elements in this group? cesium and francium
h. What happens when they are exposed to water? They react strongly/
explode.
13. Go back and click on Alkaline Earth Metals (left bar) and answer these
questions.
a. What is the group number? 2
b. Are these metals reactive? yes
c. Do these metals occur freely in nature? no
d. How many electrons are in their outer shell? (Hint: it's the same as their
oxidation number or group number.) 2
14. Go back and click on Transition Metals (left bar) and answer these questions.
a. How many elements are in this group? 38
b. What are the group numbers? 3 through 12
c. What are valence electrons? Electrons in the outer orbit, they are involved
in forming compounds.
d. Because the valence electrons are present in more that one shell,
transition metals often exhibit several common oxidations states.
e. Name the three elements in this family that produce a magnetic field.
iron, cobalt, and nickel.
15. Go back and click on Other Metals and answer these questions.
a. How many elements are in this group? 7
b. What are the group numbers? 13 through 15
c. How are these other metals similar to the transition metals? Ductile and
malleable.
d. How are these other metals different to the transition metals?they don’t
exhibit variable oxidation states, valence electrons are only present in the outer
shell.
e. List three physical properties of these other metals. Solid, opaque, high
density
f. What are the oxidation numbers for this group? +3,+-4,-3
16. Go back and click on Metalloids to answer these questions.
a. On your periodic table, draw the black stair-step line that distinguishes
metals from nonmetals.
b. On your periodic table, use your pencil to lightly shade the nine elements
that share a full side with the stair-step line. These are the metalloids. Ask
your teacher if you need help before you begin.
c. Metalloids have properties of both metals and non-metals.
d. Define semiconductor. They have the ability to conduct electricity under
special conditions.
e. Name two metalloids that are semi-conductors. silicon and germanium
f. This property makes metalloids useful in computers and calculators.
17. Go back and click on Nonmetals to answer these questions.
a. What are the group numbers? 14 through 16
b. List four characteristics of ALL nonmetals. Poor conductors of heat and
electricity, brittle, dull, can’t be rolled or pounded into sheets.
c. What two states of matter do nonmetals exist in at room temperature?
gas and solid.
d. The nonmetals have no metallic luster and do not reflect light.
e. What are the oxidation numbers of the nonmetals? +-4, -3,-2
18. Go back and click on Halogens to answer these questions.
a. What is the halogen group number? 7
b. Are halogens metals or nonmetals? Non-metals
c. The term "halogen" means salt former and compounds containing halogens
are called salts.
d. How many electrons are in their outer shell? 7
e. What is their oxidation number? -1
f. What states of matter do halogens exist in at room temperature? Solid,
liquid, gas
19. Go back and click on Noble Gases and answer these questions.
a. What is the group number? 18
b. Why were these gases considered to be inert or stable? Because their
valence level is filled, an oxidation number prevents noble gases from forming
compounds.
c. What is their oxidation number? 0
20. Go back and click on Rare Earth Elements and answer these questions.
a. On your periodic table, label the Lanthanide and Actinide series with your
pencil.
