2. I made the PERIODIC TABLE !
I am Dmitri Mendeleev!
I made the PERIODIC TABLE !

3. What is the PERIODIC TABLE?
Shows all known elements in the universe.
Organizes the elements by chemical properties.

4. How do you read the PERIODIC TABLE?

5. What is the ATOMIC NUMBER?
The number of protons found in the nucleus of an atom.

6. What is the SYMBOL? An abbreviation of the element name.
The Symbol will be a Capital letter or a Capital and lowercase letter
S-Sulfur Si-Silicon
SI-Sulfur and Iodine

7. What is the ATOMIC WEIGHT?
The number of protons and neutrons in the nucleus of an atom.

8. How do I find the number of protons, electrons, and neutrons in an element using the periodic table?
# of PROTONS = ATOMIC NUMBER
# of ELECTRONS = ATOMIC NUMBER
# of NEUTRONS = ATOMIC WEIGHT
- ATOMIC NUMBER

9. Now you are almost as smart as I am!
But not as handsome!
Man, I look GOOD!

10. Elements, Compounds, and Mixtures

11. What is an ELEMENT? A substance composed of a single kind of atom.
Cannot be broken down into another substance by chemical or physical means.

12. What is a COMPOUND?
A substance in which two or more different elements are CHEMICALLY bonded together.

13. What is a MIXTURE?
Two or more substances that are mixed together but are NOT chemically bonded.

20. Atom- The smallest particle of an element maintaining the chemical identity of that element.

21. Substance- Any form of matter that is uniform throughout and has consistent properties.

22. Lithosphere
The solid Earth, is made mostly of oxygen and silicon.

23. Hydrosphere
All water on Earth and glaciers, made mostly of oxygen and hydrogen, the two elements in pure water.

24. Biosphere
The sum of all living matter, made of including oxygen, carbon, hydrogen,nitrogen, calcium, and phosphorus.

25. Atmosphere
The layer of gas surrounding planet Earth, held in place by gravity and composed mostly of nitrogen and oxygen.

26. Matter
Has mass and takes up space, occurs as elements, compounds, and mixtures.

27. Property
Physical and chemical characteristics of matter used to describe or identify a substance.

28. Volume
Measures how much space the matter occupies.

29. Mass
Measures how much matter
is present in a substance.

30. Uniform
Composition
Made of the same evenly distributed substance or
combination of substances throughout.

31. You are still not as handsome as the great Mendeleev!
I am working this beard!
Man, I look GOOD!
