Multiple Choice

Which of these is not a noble gas?

• Helium
• Argon
• Nitrogen
• Krypton

Explanation Slide...

Noble gases are found on the far right of the periodic table in group VIIIA. Halogens are in the second group from the right. Metals of all types are found around the left side of the periodic table. There may be earth, transition, or alkaline earth metals across the table.

Explanation Slide...

All of these choices are different types and families of elements. Inert gases can be found on the far right of the periodic table in group VIIIA. Halogens are just to the left in VIIA. Metals make up the center and left side of the table in a variety of groups.

Explanation Slide...

The rows of the periodic table are called periods. The columns of the periodic table are called groups. Periods are loosely organized by the number of atomic orbitals found in each element. For example, hydrogen (H) in the first row has only one orbital. Lithium (Li) in the second row has electrons in two orbitals. Francium (Fr), in row seven, has electrons in seven orbitals.

Multiple Choice

6.15: Which of these is not a property of noble gases?

• Colourless

• Odourless

• Flammable

• Gas at room temperature

Multiple Choice

How many elements are in the Noble Gas family?

• 24
• 13
• 6
• 18

​Compound

• Elements can chemically combine to form new, pure chemical substances. 

• A chemical substance that is made of two or more different elements that chemically combine together is called a compound

• The force between compounds is STRONGER than between mixtures​

• Contain one or more substances NOT bonded together

• ​Can be separated physically

• Retains many of the properties of the components

Record the information above on your note-taker.

Mixtures

​

​Mixture

• A compound is NOT the same as a mixture

• A mixture is a physical combination of two or more different chemical substances.

• A compound is a chemical combination of two or more different chemical substances (specifically, elements)

• Unlike an element and compound, a mixture is NOT a pure chemical substance

Multiple Choice

A combination of two or more substances that can be separated is a

• potion

• mixture

• solute

• compound

Multiple Choice

Substance dissolved in a solution

• concentration
• solute
• solvent
• solution

Multiple Choice

Capable of being dissolved

• Soluble
• concentration
• colloid
• molarity

Multiple Choice

In sweet tea the solvent would be

• water

• tea

• sugar

• lemon

Multiple Choice

When a certain amount of solvent cannot hold any more solute it is called a ________ solution.

• Diluted
• Saturated

Concept Map of Classifying Matter

Recall

• Mixtures are a combination of substances

  • Can heterogenous or homogenous

    • Heterogenous Mixtures: large particles that ​can be easily seen and separated

      • Suspensions: a heterogenous mixture that separates on its own over time

        • Clay in water

      • Colloids: a heterogenous mixture that does not separate on its own over time

        • Milk

Homogenous solutions are Solutions

• Solution: any mixture that is homogenous on a microscopic level

  • Usually a liquid, but can be solid or gas as well

    • Solid solutions tend to be alloys like brass

  • ​Liquids Solutions have two parts

    • Solvent: The main ingredient that you dissolve substances in

      • Water is called the universal solvent because it dissolves so many things into aqueous solutions

    • Solute: the ingredient you are dissolving

Multiple Choice

The ______ contains a dispersed phase and a dispersing medium.

• colloids

• solute

• solvent

• solution

Multiple Choice
