11.1 Organizing By Properties

Explain how the following scientists contributed to the development of the periodic table:

Mendeleev-

Moseley:

State the periodic law-

11.2 The Modern Periodic Table

Horizontal rows are called ______.

Vertical columns are called ______or ______.

Chemical Families:

Identify the location of each of the following groups:

alkali metals-

alkali earth metals-

representative elements-

transition metals-

inner-transition metals

How are other groups on the table named ?

11.3 Patterns for Representative Elements

What are valence electrons and core electrons?

How can you determine the number of valence electrons by looking at the periodic table?

11.4 Patterns for Representative Element Ions

Why are noble gasses unreactive?

What is meant by the term isoelectronic?

Fill in the following:

# valence electrons # electrons it will loose/gain Ion Charge

Alkali metals ______

Alkaline Earth Metals ______

Halogens ______

Forming Ions :

Metals ______electrons and nonmetals ______electrons when they react together.

11.5 Patterns for Transition Elements and Ions

Fourth period transition elements

Why do unexpected configurations occur?

Ion Formation

Transition metals tend to form more than one ion. Why?

Where does the electron lost first come from?

11.6 Atomic and Ionic Radii Trends

Trends in atomic radii

Name two:

1.

2.

Explain these trends.

The first trend is because -

The second trend is because-

What effect does shielding have?

Ion size versus atom size

What is the general trend for the formation of ions?

Positive ions are ______than the atom.

Negative ions ______than the atom.

11.7 Ionization Energy

Ionization energy changes across a period

As you move from left to right across a period the first ionization energy ______.

This is because-

Deviations in the trend

What do these deviations depend on?

Why is it easier to remove an electron from a 3p orbital than a 3s?

Ioniztion energy within a group

As you go down a group the first ionization energy ______.

This is because-

Successive ionization energies

The ionization energy for each successive energy level becomes ______.

You need to be familiar with this chart and the reasoning behind all of the trends.
