Periodic Table

Getting to Know the Periodic Table

Multiple Choice

The elements are listed on the periodic table in order of ______.

• Atomic mass

• Atomic number

• State of matter

• Abundance on Earth

The way the Periodic Table is organized tells us about the elements.

​

​The horizontal rows are called periods.

​The period number tells us how many shells an atom has.

Multiple Choice

How many periods are on the periodic table?

• 3

• 7

• 9

• 18

The vertical columns are called groups.

The group tells the number of valence electrons in an atom.

Only look at the ones place of the group number!

Multiple Choice

What does the group tell us about an atom?

• How many total electrons it has

• How many electron levels it has

• How many valence electrons it has

Multiple Choice

What are valence electrons?

• The ones closest to the nucleus

• The ones on the outside

Multiple Choice

How many groups are on the periodic table?

• 3

• 7

• 9

• 18

All the elements that are LEFT of the stair step line are metals, except hydrogen.
Color these on your sheet.

Metals

All the elements that are RIGHT of the stair step line are nonmetals, as well as hydrogen.
Color these on your sheet.

Nonmetals

The elements along the stair step line are metalloids.
Color these on your sheet.

Metalloids

Multiple Choice

What is hydrogen?

• metal

• nonmetal

• metalloid

Multiple Choice

Groups/Families

Metals and nonmetals can be broken into smaller groups, based on their properties and location on the periodic table. We will only look at a few of these.

All the elements in the first group (except hydrogen) are alkali metals. They are VERY reactive.
Color these on your sheet.

Alkali Metals

All the elements in the second group are alkaline earth metals. They are really reactive, but not as much as alkali metals.
Color these on your sheet.

Alkaline Earth Metals

All the elements in the 17th group are halogens. They are VERY reactive.
Color these on your sheet.

Halogens

All the elements in the 18th group are noble gases. They are unreactive.
Color these on your sheet.

Noble Gases

All the elements in the middle section are transition metals. These are "typical" metals like gold, iron, copper.
Color these on your sheet.
