1. Elements

2. Standards Covered GLE 0807.9.2 Explain that matter has properties that are determined by the structure and arrangement of its atoms. SPI 0807.9.3 Classify common substances as elements or compounds based on their symbols or formulas. GLE 0807.9.4 Distinguish among elements, compounds, and mixtures.

3. Standards Covered Check-0807.9.5 Distinguish between elements and compounds by their symbols and formulas. GLE 0807.9.6 Use the periodic table to determine the characteristics of an element. SPI 0807.9.9 Use the periodic table to determine the properties of an element.

4. What Are Elements? An element is the type of atom you have. An atom is the smallest amount of an element you can have. There is only one type of atom per element.  Pure gold is made of only gold atoms.  Pure iron is made of only iron atoms.

5. Let me rephrase that… All atoms have the same 3 types of parts, but what element it is depends on how many electrons, protons, and neutrons it has. I have even heard students say.. “ All atoms are Elements… and Elements are just the specific names of Atoms…”  They are not wrong…

6. To repeat… Element is just another way of saying the type of atom you have. It’s being specific… every element is in the form of an atom but only one element has correct number of electrons, protons, and neutrons to be a “ Carbon Atom.”

7. Let’s approach it from another angle… Think of it this way…  You can call every male a boy and not be wrong…  However, they all have different characteristics (some tall, some skinny, some big, some hairy…)  So why not be more specific? Calling something an atom is broad. Calling it the element name is specific.

8. Let’s go back to the chart…

9. More about Elements.. Elements (since elements are basically specific atoms) are the building blocks of all matter. The periodic table is a list of all of the elements that can build matter. It’s a little like the alphabet of elements/ atoms. The periodic table tells us several things…

11. Periodic Table 8 O Oxygen 16 Atomic Number: Number of protons and it is also the number of electrons in an atom of an element. Element’s Symbol: An abbreviation for the element. Elements Name Atomic Mass/Weight: Number of protons + neutrons.

12. Periodic Table Info… Balanced atoms have the same number of protons and electrons, all the elements on the periodic table are balanced. The atomic number is the number of protons in an atom. Copyright © 2010 Ryan P. Murphy

13. Atoms always have the same number of protons and electrons, this is called the atomic number.

19. Atoms always have the same number of protons and electrons, this is called the atomic number. Copyright © 2010 Ryan P. Murphy All atoms must be electrically balanced. The same number of negative electrons and positive protons, if they were not equal then the Atom would have a charge,

20. Atoms always have the same number of protons and electrons, this is called the atomic number. Copyright © 2010 Ryan P. Murphy All atoms must be electrically balanced. The same number of negative electrons and positive protons, if they were not equal then the Atom would have a charge, it would then not be stable and instantly need to react.
