1. Learning Outcomes
For this learning guide, you should be able to:
explain the periodic recurrence of similar properties
among elements in the periodic table in terms of
electronic structure;
relate the number of valence electrons of elements to
their group number in the periodic table;
compare the properties of families of elements;
predict the properties of individual elements based on
their position in the periodic table;
describe and explain the trends in atomic properties in
the periodic table.

2. Introduction
This learning guide is intended for the
learners demonstrate an
understanding of the arrangement
of elements in the periodic table and
trends in the properties of the
elements in terms of electronic
structure.

3. Lesson Proper
What is a periodic table?
The periodic table is a
chart in which elements
having similar chemical
and physical properties
are grouped together.
The elements are
arrange according to
increasing atomic
number.

13. What is an element block?

19. Guided Practice

20. Na period 3, family 1

21. Asynchronous Activity
Outline the portion referred to by each of the terms on the blank
periodic table below, then label each outlined part with the term.
representative elements
nonmetals
metalloids
transition elements
inner transition elements
In the periodic table, write the letter of each of the above elements in
the space provided before its description. Each response can only be
used once.
____1. A transition element
____2. An alkaline earth metal
____3. Most nonmetallic element
____4. An alkali element
____5. Element with the biggest atomic radius
____6. A noble gas
____7. A metalloid
____8. An element with the highest first ionization energy
____9. A halogen
____10. Can lose or gain one electron

22. Consider the electron configurations for neutral atoms listed below. Determine which atoms have electron configurations that describe their
properties.
Highest first ionization energy
1.
largest atom
2.
highest electron affinity
3.

7.
found in period 4
8.
most number of unpaired electron
9.
a metalloid
10.
