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

2nd Period

6th Period

Family (or Group): arranged vertically down the periodic table (columns or group, 1- 18 or 1-8 A,B)These elements have the same number electrons in the outer most shells, the valence shell.

Alkali Family: 1 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)

Without looking at a periodic chart:•What can you determine about this element:1s22s22p3? •What element is it?

•It is in the 2nd period•It has 5 valence electrons•Has 7 electrons & (probably) 7 protons•Is in the 5A group•Is in the P block of elements•Nitrogen

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
