What does an element’s location in the periodic table tell you about that element?

An element’s location on the periodic table tells about the element’s properties.

What would happen if protons were added to an atom?

It would become a new element.

What reactivity pattern do the metals follow on the periodic table?

As you move from the left to the right, the reactivity of the metals decreases.

Use the periodic table to name two elements that you would expect to have properties very much like those of calcium.

Two of the following: Beryllium Magnesium Strontium Barilium Radium

Name three properties of metals.

Shiny Malleable Reactive Conductive Ductile

Which group is the Alkaline Earth Metals?

Group 2

What makes an atom neutral? Be specific.

The number of positively charged protons is equal to the negatively charged electrons.

What did Mendeleev discover while developing the periodic table?

The periodic table is full of patterns among the elements.

What is the name of Group 1?

Alkali metals

What are the three subatomic particles found in the atom?

Protons Neutrons Electrons

How many shells are found in Xenon (54)?

Xenon has 5 energy shells.

Why are the Alkali metals never found uncombined in nature?

They are too reactive.

Where are the lanthanides and actinides located on the periodic table?

The lanthanides and actinides are located below the main part of the periodic table.

What can the period number tell you about an atom?

The period number can tell you how many energy shells are in the atom.

What can a group number tell you about an atom?

The group number can tell you how many valence electrons an atom has.

Is Phosphorus (15) more similar to Antimony (51) or Sulfur (16)? Why?

Phosphorus is more similar to Antimony because they are in the same family.

How many valence electrons are found in Calcium (20)?

2 valence electrons

What is an alloy?

A mixture of metals.

Why is carbon so important to us?

We are carbon- based life forms. We use carbon in many fuels.

How do we synthesize elements?

We collide nuclei together in a particle accelerator.

What are the nonmetals in the Carbon family?

Carbon (only)

Where would you classify hydrogen? Why?

Hydrogen is in a group of its own – it does not share the properties of the other elements.

What is conductivity?

The ability to pass electricity or heat through it.

Where is most of the mass of an atom?

Most of the mass of an element is found in the nucleus.

Give two examples of how nonmetals differ from metals.

Nonmetals are brittle, dull, non conductive, have lower densities, and are poor conductors.

What family of elements in the periodic table contains the most reactive metals?

Alkali Metals (Group 1)

Why is the oxygen family so important to us?

We need oxygen to survive.

Which group will the Halogens most likely combine with?

Alkali Metals (Group 1)

What particles are in the center of the atom?

How many neutrons does the most common isotope of Carbon have? 6 C Carbon

6

Where in the periodic table are the metalloids found?

Along the zigzag line (except Aluminum)

Give an example of how the ductility of a metal can be useful.

The transition metals are groups 3-12 on the periodic table.

Where are the transition metals located on the periodic table?

It allows the metal to be drawn into wires for electrical wires and jewelry.

How are the elements arranged in a modern periodic table?

They are arranged in order of increasing atomic number.

What property of the materials used in computer chips makes them useful as switches that turn electricity on and off?

The fact that the element has a varying ability to conduct electricity.

Are the alkaline earth metals more or less reactive than the alkali metals? How do you know?

The alkaline earth metals are less reactive than the alkali metals. You know because they are to the right of the alkali metals on the periodic table.

How do the noble gasses differ from the rest of the periodic table?

The noble gasses have complete valence shells – therefore, they are unreactive.
