1. Cornell Notes: The Periodic Chart
2. Practice3. Assign Homework
Periodic Table:
A systematic catalog of elements.
Elements are arranged in order of atomic number.
Periodicity
When one looks at the chemical properties of elements, one notices a repeating pattern of reactivities.
Periodic Table
The rows on the periodic chart are periods.
Columns are groups.
Elements in the same group have similar chemical properties.
Periods: arranged horizontally across the periodic table
(rows 1-7) These elements have the same number of
valence shells (Energy Levels).1

Alkali Family: 1 e- in the valence shell
Halogen Family: 7 e- in the valence shell
Halogen Family: 7 e- in the valence shell
Groups
These five groups are known by their names.
Periodic Table
Nonmetals are on the right side of the periodic table (with the exception of H).
Periodic Table
Metalloids border the stair-step line (with the exception of Al and Po).
Periodic Table
Metals are on the left side of the chart.
Periodic Table: The three broad ClassesMain, Transition, Rare Earth
Main (Representative), Transition metals, lanthanides and actinides (rare earth)

1. Notes: Periodic Trends2. Homework Questions3. Classwork/Project Assignment
Trend in Atomic RadiusAtomic Radius: The size of an atom as determine by the boundaries of the valence e-.Largest atomic species are those found in the left bottom corner
• Why does the trend decrease across a period?
• Why does it increase down a group?
As you move across a period the # of protons increases. The
positive charge of the protons attracts the electrons, pulling the
electrons in tighter
As you move down the group the size of
atom increases
Trend in Ionization PotentialIonization potential:
• The energy required to remove the valence electron from an atom.
• Largest toward top right corner since these atoms hold on to their valence e- the tightest.
Trend in Electron Affinity
Electron Affinity:
• The energy released when an electron is added to an atom.
• Most favorable toward top right corner
Summary of Trends
Atomic Radius: Increases
Ionization Energy: increasesElectron Affinity: Increases
