ORGANIZING MATERIALS

P. 126-133

§4.1: LEARNING GOALS

Content

• I know what an element is
• I know the first 20 elements of the periodic table by name and symbol
• I know the properties of metals, non-metals and metalloids
• I know where the metals, non-metals and metalloids are in the periodic table

Language

• I can use the properties of metals, non-metals and metalloids to explain why they are suitable to use for different purposes.

Skills

•  I can classify if an element is a metal, non-metal or metalloid by looking it up its location in the periodic table
•  I can use the atomic masses of the elements to calculate the mass of a molecule

§4.1: LEARNING GOALS

LG - Step 1: Read the learning goals above carefully. In the 3rd column mark the ones you feel good about with a “+” and the ones you might be a bit worried about with a “-”.

LG - Step 2: Take a good look at the categories of learning goals and compare them to your scores from S1. Now rank your categories from strongest to weakest using the letters A, B & C. (A - being strongest.)

LG - Step 3: Discuss what you have just filled in on your table with your neighbour(s). Try to explain / argue why you made that choice and ask the person for clarifying questions if need be.  

LG - Step 4: Think about what you have just discussed. Make any necessary changes in the marking of your table if need be. Use the last column please!

LG - Step 5: Based on the steps you have just completed, take a look at the table below. What 3 things / goals are you going to focus on this paragraph? Please write them down below.

§4.1: KEY WORDS

• elements
• periodic table
• atomic number
• atomic mass
• metals
• metalloids
• non-metals

P. 126-133

§4.1: ELEMENTS

• Elements are the building blocks of the universe
• 118 elements, 92 occurring naturally
• Can’t be broken down into smaller substances
• Organized in a table

P. 126-133

§4.1: THE PERIODIC TABLE

• All elements are organized in the Periodic Table.
• Each element is given its own number, called an atomic number

• The table is divided into 3 categories
• Metals
• Non-metals
• Metalloids

P. 126-133

§4.1: METALS

There are around 90 metals in the periodic table. 

Metals have the following properties:

• Dense (high density)
• Shiny
• Good conductors (easily spread heat or electricity)
• High melting point  (solid at room temperature, except Mercury)
• Malleable (easily bent without breaking)
• Metallic lattice structure
• Atoms are organized neatly in rows 

P. 126-133

§4.1: NON-METALS

There are around 20 non-metals in the periodic table

Non-metals have the following properties:

• Low density
• Dull surface
• Poor conductors (don’t spread heat or electricity)
• Low melting point (Mostly gases at room temperature) 
• Brittle (Don’t bend but break)

P. 126-133

§4.1: METALLOIDS

Metalloids are between metals and non-metals on the periodic table, therefore they share properties of both groups. 

Most metalloids are:

• Shiny
• Brittle
• Poor conductors

• These properties are different for each metalloid.
