Cl

• Two or more atoms bonded (attached) (chemical forces)

• Smallest unit of any compound that keeps the properties of that compound.

Covalent Bond

• A pure substance • A substance made up of

atoms from two or more bonded elements.

Ionic Bond

• A combination of two or more substances blended together

• No set ratio of ingredients

• Homogeneous: 2 or more things evenly blended and disappear into each other.

• Solute – Smaller quantity• Solvent – Larger quantity• Solution – a homogeneous

mixture

• Heterogeneous: 2 or more things put together and still can be seen.

• No set RATIO.

• We know the definition of Element, Compounds & Mixtures

• What do their particles look like?

Compound

Mixture

Element

Compound

Can you create your own?

• 2 different samples of Elements• 2 different samples of Compounds• 2 different samples of Mixtures

1. Mixture of Elements, 2. Mixture of Compounds or 3. Mixture of Elements and Compounds

• Materials Managers: Pick up one supply bag for your table

• Separate and Layout 6 small zip lock bags labeled, ELEMENT, COMPOUND, MIXTURE, Supplies

• Build: A 2 examples of each

• Your table should have:– 2 diff. examples of Element

Particles– 2 diff. examples of Compound

Particles– 2 diff. examples of Mixtures

• Mixture of Elements• Mixture of Compounds• Mixture of Elements and Compounds

– Get a Signature from Mrs. M.

• Complete Venn Diagram ONLY – We will finish the rest in class tomorrow – Due by the end of the period tomorrow

• Correct Test #3 and Get Signed – Due tomorrow
