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 becauseDeviations 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 becauseSuccessive 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.
