DACUM CHART, PRINCIPALS OF PERIODIC TABLE
DACUM Title: Principals of Periodic Table of Elements

Explain the periodic
table of elements and
state its general
properties

group I, name them and
state properties of this
family of elements

Analyze elements of
group VII, name them
and state properties of
this family of elements
D
Analyze family of
Transition Metals and
state properties of this
block of elements

Analyze elements of
group 0, name them and
state properties of this
family of elements
A1: Place the elements of
periodic table according to their
atomic number into Groups and
Periods
B1: Analyze the presence of only
single electron in outer shell of
elements of this group which
results in formation of single
positive ions
C1: State the number of
electrons in the outer shell of
elements of group VII and its
importance in their reactivity
D1: State the position of these
elements as ten short groups
between main groups II and III of
periodic table
E1: State the name of group 0 of
periodic table and emphasize on
owning full outer shell of
electrons
A2: State the chemical
similarities of the elements
belonging to the same group
B2: State the name of group I
and explain the reason by which
they are called "Alkali Metals"
C2: State the name of group VII
of elements and state the product
of their reaction with reactive
metals
D2: State the hardness of these
elements as a typical property
and emphasize on the fact that
they have many industrial
applications
E2: Specify these elements as the
most unreactive elements of
periodic table
A3: Analyze the arrangement of
elements in periodic table by
increase in their atomic number
B3: State the softness of
elements of group I as a specific
property of these metallic
elements
C3: Analyze trend in change in
color and density of elements of
group VII
D3: State the formation of
colored compounds
E3: Analyze the importance of
their underactivity to make them
very useful in industrial usages
A4: Analyze the trend of change
in metallic property to nonmetallic property moving across
a period
B4: Analyze the trend of increase
in metallic properties of elements
of group I down the group
C4: Analyze the trend of
increase in reactivity of nonmetals moving up group VII
D4: State the property of this
metals by which they are used in
many industrial processes such as
Haber and Contact process
E4: State their physical state in
room temperature and name one
usage of Helium
A5: State the number of
electrons in outer shell of an
elements determines the
number of group of the element
B5: Analyze the reactivity of
elements of group I
C5: Compare the position of this
group with other groups of
periodic
D5: Analyze some popular metals
of this block such as Gold and
Silver which are used in jewelry
industries
E5: Analyze Argon and Neon as
two examples of most important
elements of this group

Performance Objectives
-
A2: State the chemical similarities of the elements belonging to the same group.
(PO): Given a periodic table, without the aid of class notes, students will be able to state the chemical similarities of the elements belonging to the same group, with no errors.
-
A3: Analyze the arrangement of elements in periodic table by increase in their atomic number
(PO): Showing a magnified diagram of an element symbol including its atomic mass and atomic number placed in their right position, students will be able to analyze the arrangement of elements in periodic
table by increase in their atomic number, not their atomic mass.
-
A4: Analyze the trend of change in metallic property to non-metallic property moving across a period
(PO): Given a large periodic table attached on the board of class, students will be able to analyze the trend of change in metallic property to non-metallic property moving across a period, from left of periodic
table to right
-
A5: State the number of electrons in outer shell of an elements determines the number of group of the element
(PO): Emphasizing on concept of outer shell electrons, students are supposed to be able to state the number of electrons in outer shell of an elements determines the number of group of the element, not the
number of shells of element.
-
B2: State the name of group I and explain the reason by which they are called "Alkali Metals"
(PO): In a lab environment and using a pH meter, students will see the experiment to state the name of group I and explain the reason by which they are called "Alkali Metals", after observing the change in pH
of solution to alkali region.
-
B3: State the softness of elements of group I as a specific property of these metallic elements
(PO): In a lab environment, students will see the experiment to analyze the softness of metals of group I, as a special properties of metals, opposite of other metals which are hard
-
B4: Analyze the trend of increase in metallic properties of elements of group I down the group
(PO): Providing some examples of typical reactions of elements in a group and comparing them, students learn to analyze the trend of increase in metallic properties of elements of group I down the group, in
right direction.
-
B5: Analyze the reactivity of elements of group I
(PO): Given group I elements, students will be able to analyze their reactivity, specifically when they come in contact with water
-
C3: Analyze trend in change in color and density of elements of group VII
Page |3
DACUM CHART, PRINCIPALS OF PERIODIC TABLE
(PO): Using examples such as Fluorine as a gaseous element with yellow color at the top of the group and Iodine as a solid element and black color at button of this group, students will be able to analyze trend
in change in color and density of elements group VII, with no errors
-
C4: Analyze the trend of increase in reactivity of non-metals moving up group VII
(PO): Using an example such as Fluorine as the highest reactive non-metal at the top of the group, students will learn to analyze the trend of increase in reactivity of non-metals moving up group VII, in right
direction
-
D3: State the formation of colored compounds
(PO): Using an example such as blue crystals of hydrated copper sulfate, students will be able to state the formation of colored compounds when transition elements react with other elements to form
compounds, as the specialized property of transition elements not other groups
-
D5: Analyze some popular metals of this block such as Gold and Silver which are used in jewelry industries
(PO): In a lab environment, students will analyze argon and neon, including essential characteristics and applications to jewelry industry
-
E2: Specify these elements as the most unreactive elements of periodic table
(PO): Reminding the presence of full outer shell of electron which causes stability of elements, the students will be able to specify these elements as the most unreactive elements of periodic table because their
outer shell is full of electrons, as the main reason.
-
E3: Analyze the importance of their underactivity to make them very useful in industrial usages
(PO): Using some examples such as use of Helium to fill the balloons, the students will learn to analyze the importance of their underactivity to make them very useful in industrial usages, trying to state other
correct examples
-
E5: Analyze Argon and Neon as two examples of most important elements of this group
(PO): In a lab environment, students will analyze argon and neon, including essential characteristics and applications to lighting industry for filling the light bulbs
