You will be allowed to use your foldable periodic table on the test.

Where on the Periodic Table are the most metallic elements located?

Bottom left

What are nonmetals?

Nonmetals are elements that have no metallic properties.

Where on the Periodic Table are nonmetals located?

Nonmetals are located on the right.

At room temperature, most nonmetals are in which state of matter?

Gaseous

In which periods are metals located on the Periodic Table?

2-7

List the alkali metals

Lithium, sodium, francium, potassium, rubidium

How is the Periodic Table arranged using atomic numbers?

The atomic numbers increase going from left to right across periods.

Which 4 factors did Mendeleev use to arrange his Periodic Table?

Density, color, melting point, atomic mass

Define periodic table.

The periodic table is a chart of elements arranged into rows and columns (periods and groups) according to their physical and chemical properties.

What is the definition of atomic number?

The number of protons in the nucleus of an atom.

How did Moseley organize his periodic table?

Moseley organized his periodic table by increasing atomic numbers.

Be able to identify an element's name, atomic number, atomic symbol, and atomic mass, and state of matter by looking at the periodic table.

See page 98 of your notes for this.

What are groups on the periodic table?

columns

What are periods on the periodic table?

rows

Explain how scientists are able to determine a synthetic element's properties.

Scientists are able to look at the properties of other elements in the same groups and period to determine the properties of the synthetic element.

Define luster.

the ability to reflect light

Define conductivity.

the ability to conduct heat and electricity

Define ductility.

the ability to be pulled into thin wires

Define malleability.

the ability to be hammered or rolled into thin sheets

Alkali metals are in which group?

Group 1

Do alkali metals react quickly or slowly with other elements?

quickly

Are alkali metals found in nature as elements, in compounds, or both?

Compounds

What type of appearance do alkali metals have?

dull

Are alkali metals soft or hard?

soft

Describe the density of alkali metals.

They have the lowest densities of all of the metals.

What type of metals have the lowest densities?

Alkali metals

How are alkali metals and alkaline earth metals different. Use the following words: group, reactivity (or reactive), density.

Alkali metals are in group 1. Alkaline earth metals are in group 2. Alkali metals are extremely reactive. Alkaline earth metals are very reactive, but not as reactive as alkali metals. Alkali metals have the lowest densities of all metals. Alkaline earth metals have a low density, but it is not as low as alkali metals.

How are alkali metals and alkaline earth metals similar?

They are both found in nature only as compounds. They are both soft metals. They are both silvery in color.

Where on the Periodic Table are Transition Elements located?

They are located in groups 3-12

What are the properties of transition elements?

great strength, high melting points, high densities, less reactive than other metals

What are lanthanides used for?

strong magnets

What are actinides used for?

fuel in nuclear reactions

Describe the arrangement of metals in the periodic table in terms of their properties.

Metallic properties decrease from left to right across the periods.

The human body is made up of mostly (metals, nonmetals)

Nonmetals

96% of the mass of the human body is made up of what 4 elements?

oxygen, nitrogen, carbon, and hydrogen

What are nonmetals?

elements that have no metallic properties

Solid nonmetals have what type of surface?

Dull (no luster)

What is the nonmetal that are in group 14? (you will use your periodic table for this)

Carbon

What are the nonmetal that are in group 15? (you will use your periodic table for this)

Nitrogen, phosphorous

What are the nonmetal that are in group 16? (you will use your periodic table for this)

Oxygen, sulfur, selenium

In which group are the halogens?

group 17

What is the name of the group 17 elements?

Halogens

Are halogens found in nature as elements, in compounds, or as both?

Compounds

With what type or types of elements do halogens react?

Metals and nonmetals

What it the resulting compound called when a halogen reacts with a metal?

Salt

As you move down the halogens group, what happens to the reactivity?

It decreases.

As you move up the halogen group, what happens to the reactivity?

It increases.

In what goup are the Noble Gases?

Group 18

What are the group 18 elements called?

Noble Gases

Why weren't the noble gases included in Mendeleev's periodic table?

They weren't discovered until after Mendeleev constructed his periodic table.

Are noble gases found as elements, in compounds, or as both in nature?

Only as elements.

Explain how hydrogen shows properties of both metals and nonmetals.

In its liquid form, hydrogen conducts electricity like a metal. It is very reactive like an alkali metal. Like some nonmetals, it is a gas at room temperature. Under the conditions found on Earth, hydrogen acts as a nonmetal.

Define metalloid.

an element that has physical and chemical properties of both metals and nonmetals

How are metalloids like metals?

they coduct electricity at high temperatures

How are metalloids like nonmetals?

they stop electricity from flowing at low temperatures

Define semiconductor.

A semiconductor conducts electricity but not as well as a metal does

How is a semiconductor useful?

A semiconductor is useful in electronic devices because it conducts electricity well at high temperatures and stops electricity from flowing at lower temperatures.

Be able to tell an element's atomic number whether it's a metal, nonmetal, or metalloid; and which group and period it is in by using your foldable periodic table.
