Tuesday, March 31Do Now:

What is the difference in homogeneous and heterogeneous mixtures?

Give an example of each.

Page 2: Tuesday, March 31 Do Now: What is the difference in homogeneous and heterogeneous mixtures? Give an example of each

Objective:

I can define atom, atomic mass, and atomic number.

I can explain how the elements are arranged on the periodic table.

Page 3: Tuesday, March 31 Do Now: What is the difference in homogeneous and heterogeneous mixtures? Give an example of each

What are Elements?

Use the Chemical Building Blocks Book

Define: Elements Compounds

Page 4: Tuesday, March 31 Do Now: What is the difference in homogeneous and heterogeneous mixtures? Give an example of each

How many elements are there?

Over 100 (currently 113)

How are we able to arrange the elements so that they can be understood?

Dmitri Mendeleev Russian Scientist 1869

Noticed that the elements displayed interesting patterns

He wrote out properties for each element and used those prop. to put them into a table.

Dmitri Mendeleev

Recognized a pattern for the table: Phy/Chem properties Atomic mass Bonding power

Page 8: Tuesday, March 31 Do Now: What is the difference in homogeneous and heterogeneous mixtures? Give an example of each

Wednesday, April 1Do Now: Write the answer only.

How did Mendeleev set up the periodic table?

Based upon atomic mass Chemical/physical properties Bonding power

Quick Homework Check:

If you did not complete the homework please fill in a choice on your choice card.

You are expected to finish this today during class before doing the task for today.

Copy: p.120-135

Where is it located on periodic table?

How reactive is this family? What are some physical properties

of this family? Can you give a place in the world

where we can find these?

Thursday, April 2Do Now:

Use the science book to define:

Solute Solvent

Page 13: Tuesday, March 31 Do Now: What is the difference in homogeneous and heterogeneous mixtures? Give an example of each

Examples:

The Solute is what is dissolved—it is the lesser amount. Ex. Sugar

The Solvent is what does the dissolving… it is in the greater amount. Ex. of Solvent is Water

Metals:

Physical Properties of Metals: Luster (shininess) Good conductors of heat and electricity High density (heavy for their size) High melting point Ductile (most metals can be drawn out

into thin wires) Malleable (most metals can be

hammered into thin sheets)

Metals continued:

Page 27: Tuesday, March 31 Do Now: What is the difference in homogeneous and heterogeneous mixtures? Give an example of each

Nonmetals

Physical Properties of Nonmetals: No luster (dull appearance) Poor conductor of heat and electricity Brittle (breaks easily) Not ductile Not malleable Low density Low melting point

Page 28: Tuesday, March 31 Do Now: What is the difference in homogeneous and heterogeneous mixtures? Give an example of each

Chemical Properties of Nonmetals Tend to gain electrons

Since metals tend to lose electrons and nonmetals tend to gain electrons, metals and nonmetals like to form compounds with each other. These compounds are called ionic compounds. When two or more nonmetals bond with each other, they form a covalent compound.

Metalloids

Physical Properties of Metalloids: Solids Can be shiny or dull Ductile Malleable Conduct heat and electricity better

than nonmetals but not as well as metals

**I will take these up before you leave…. These are not homework unless we are not using time wisely
