Introduction to the Periodic Table Families

The Periodic Table:
Groups and Periods

Multiple Choice

Mendeleev wasn't the only one to arrange the elements into some sort of a table. What did he do that no one else had done?

• He was the first to use a typewriter so his work was readable.

• He predicted the properties of undiscovered elements. And he was right!

• He grew his hair and caught on, starting the 60's hippie movement

• Created a model of an atom that explained atomic spectra.

The periodic table is composed of elements
arranged in order of increasing atomic number.

​The Periodic Table

Periods

The horizontal rows on the periodic table
are called periods.

Groups

• Elements in the same group have the same number

of valence electrons.

• Columns on the periodic table are called groups.

Multiple Choice

How are the elements arranged on the periodic table today?

• By atomic mass

• By number of electrons

• By atomic number

• By alphabetical order

Multiple Choice

A ___________ is an arrangement of elements in columns

• columns
• rows
• periodic table
• electron shell

Three Types of Elements

The periodic table contains three types of elements:
metals, nonmetals, and metalloids.

Metals

Nonmetals

Metalloids

Metals, Nonmetals, Metalloids

• Metals – hard, shiny elements that are good

conductors of heat and electricity.

• Nonmetals – soft, brittle elements that are

poor conductors of heat and electricity.

• Metalloids – share some properties of metals

and some properties of nonmetals.

Multiple Choice

Elements which are shiny, conduct electricity and heat are called

• metal
• nonmetal
• metalloid
• nonexistent

Multiple Choice

Groups of the Periodic Table

•

Elements are organized into groups (1-18).

•

Elements in the same group have similar properties.

Alkali Metals (Group 1):
Soft and shiny. Extremely reactive with water

Alkaline Earth Metals (Group 2):
Hard, shiny metals. Very reactive.

Alkali Metals

Alkaline Earth

Metals

Transition Metals (Group 3-12):

Transition Metals

Strong metals that are ductile and malleable.

Used to make common items like coins and tools.

Explanation Slide...

Semiconductors, metalloids, semimetals all refer to the same elements. They have properties of both metals and nonmetals. They are used in all of your electronic devices.

Lanthanides (Elements 57-70)
Actinides (Elements 89-102)

Also known as the Rare Earth Metals.
All metals, all solids, all radioactive.

Lanthanides

Actinides
