number of protons but with different
number of _________.
neutrons

4. How many neutrons does the following
oxygen atom have?
8

12. Guide questions:
1. What are the contents of the mixed nuts?
2. What are the characteristics of the mixed nuts
contents that made you decide to group them
together?
3. How do you relate this activity to the periodic
table?

14. What is a periodic table?
The periodic table is a graphical layout of 118 chemical
elements organized into rows and columns depending to
their basic characteristics.
Why is it important?
It is one of the most important tools in the history of
chemistry. It allows a scientist to easily grasp the
relationships and similarities among the elements which is
the building block of all matter.

16. Antoine Lavoisier
1789
 French Chemist
 Grouped the elements based on their properties into
metals and nonmetals.

17. Johann Wolfang Döbereiner
1829
 German Scientist
 Arranged the elements in groups of three in increasing
order of atomic weight and called them triads.

18. John Newlands
1863
 British chemist
 The first to arrange the elements into a periodic table with increasing order of atomic masses
and found that every eight elements had similar properties which he called the law of octaves.
 He arranged the elements in eight groups but left no gaps for undiscovered elements.

19. Dmitri Mendeleev
1869
 Russian chemist
 Created the framework that became the modern periodic table, leaving gaps for
elements that were yet to be discovered.
 He was also known as Father of the Periodic Table

20. Henry Moseley
1913
 English physicist
 Rearranged the elements in the periodic table based on atomic numbers

22. How are the elements arranged in the table?
The elements in the periodic table are arranged in rows
called periods and columns called groups according to
increasing atomic number.

23. What is a period?
 Horizontal row of the periodic table
 It is numbered 1 -7, from top to bottom.
 The period number states how many energy levels or
electron shells an element has.

The period number states how many
energy levels or electron shells an
element has.
Example Magnesium
Atomic No. : _______
Period No. : _______
Number of shells: _______
12
3
3

26. What is a group?
 the vertical column of the periodic table
 numbered 1-18, from left to right.
 also called a family because the elements tend to have
very similar physical and chemical properties
 The group number states how many valence electrons
an element has.
 An element can have a maximum of 8 valence
electrons.

28. Mg
 The group number states how
many valence electrons an
element has.
 An element can have a maximum
of 8 valence electrons.
Example Magnesium
Atomic No. : _______
Group No. : _______
Number of valence electron: _______
12
2
2

29. Names of groups/families
Group 1: Alkali Metals
Group 2: Alkaline Earth Metals
Group 13: Boron Group
Group 14: Carbon Group
Group 15: Nitrogen Group
Group 16: Chalcogens
Group 17: Halogens
Group 18: Noble Gases
Groups 3-12: Transition Metals

While the music is playing, students should pass the paper ball
around the class. When the music stops, the student with the ball will peel
1 paper and answer the question on it.
