Periodic table trends

Periodic Table & Trends

  • Objective: To understand the physical and chemical properties of atoms based on their position on the Periodic Table

  • NC Essential Standards 1.3

  • What does “periodic” mean?


The pattern is the key

The Pattern is the Key

Put the following into a pattern

3 across

4 down

Bluebird, green hummingbird, red cardinal, pink flamingo

Pink freight truck, Red pick-up truck, green Civic, Blue SUV

Green cottage, Blue house, Red brick apartment building, Dilworth’s pink glass building


Periodic table trends

A Chemist’s Most Useful ToolHow can we use the Periodic Tableto understand the properties of elements?

Electron arrangement impacts the shape of the periodic table

Electron Arrangement impacts the shape of the Periodic Table

  • Periods

  • Groups

  • Blocks


Periodic table trends

Elements are arranged in Periods (_____) according to the total number of _________ _________ for their electrons.

b. The Periodic Table can be divided into 4 blocks based on electron configurations for the elements.

Groups Val electrons

Block S

Block P

Block D

Block F

Element groups properties

Element Groups & Properties


Ordering elements by properties

Ordering Elements by Properties

Follow the instructions on the small card

Arrange the elements based on properties

Put elements into columns and rows in a pattern

Use physical and chemical properties

Why did you put an element card at the top of a column?

Why should another be placed lower or to the right?


Results

Results?

Analyze your results:

Make a table that shows the order of your elements (see next slide)

Show the patterns for the properties

Physical properties - explain the pattern for each physical property

Chemical properties – explain the pattern


Ordering groups of elements by properties

Ordering Groups of Elements by Properties


Ion practice

Ion Practice

  • Ion Formation base on electron configuration

    • Metal or non-metal?

    • Compare atom & ion

      • Electron configuration and Electron Dot Notation

  • Additional practice

    • Using Lewis Diagrams


Representing ions

Representing Ions

  • Ions are formed when the __________ electrons are lost or gained.

  • Metals ________ valence electrons to form

    _______ ions, called __________.

    Non-metals _______ valence electrons until they have 8 and form _______ ions, called

    __________.
