1. Unit 6 Whole as Sum of Parts
Chapter 3 Lesson 1 pp

2. Basic Properties of Matter
Matter is anything that that has mass and takes up space
Properties of matter
Solubility
Mass
Hardness (Density)
Take up space

3. 3 States of Matter
Solid
Liquid
Gas

5. Particles of Matter Democritus (a Greek thinker) thought matter was:
Made of tiny particles, or bits
Different kinds of matter are made of different kinds of particles
Particles could not be broken down into smaller parts

6. The smallest possible particle of a substance is an atom.
Atoms are made of
Protons (positive charge)- located inside the nucleus
Neutrons (neutral (no) charge)- located inside the nucleus
Electrons (negative charge)- move around the outside of the nucleus

7. Atoms - Atoms have a nucleus that contain protons and neutrons -electrons orbiting the outside of the atom The attraction between the protons and the electrons keeps the atom together

8. A molecule is made up of 2 or more atoms joined together.
Atoms and molecules are do small they cannot be seen with a regular microscope because they do not reflect light.
Atom means “cannot be divided”

9. Elements
An element is a substance that is made up of just one kind of atom
There are 116 elements
Examples:
Mercury
Iron
Silver
Gold
Hydrogen
Oxygen

11. Some Groups of Elements
Scientists have grouped elements together
Example: Metals and nonmetals
However, not all metals are elements- such as steel (it is made of the elements iron and carbon)

12. Metals Metals are: Shiny Malleable- they are easy to shape or form
Ductile- they can be pulled into long thin wires without breaking

13. Nonmetals Nonmetals are: Not shiny
Brittle –cannot be pounded without breaking
Don’t conduct electricity well

14. Noble Gases Noble Gases (neither metals nor non-metals) Colorless
Odorless
Some glow when electricity is added (neon and argon)
