2. EQs 1.What is the difference between atoms, elements, molecules, and compounds? Created by G.Baker www.thesciencequeen.net

3. Matter is anything that takes up space and has mass. All matter is made of atoms

4. What are atoms? The smallest amount of an element. Atoms are the building blocks of matter, (sort of how bricks are the building blocks of houses.) Created by G.Baker www.thesciencequeen.net

5. An atom has three parts: Proton = positive Neutron = no charge Electron = negative The proton & neutron are found in the center of the atom, a place called the nucleus. The electrons orbit the nucleus. Picture from http://education.jlab.org/qa/atom_model_03.gif

6. What are elements? A basic substance that can't be simplified (hydrogen, oxygen, gold, etc...)hydrogenoxygen gold

7. What are Molecules? 2 or more atoms that are chemically joined together (H 2, O 2, H 2 O, etc...) Created by G.Baker www.thesciencequeen.net

8. What are compounds? A molecule that contains more than one element (H 2 O, C 6 H 12 O 6, etc...)

10. Summary: Created by G.Baker www.thesciencequeen.net Atoms combine to make Molecules Molecules can be either elements(2+same type of atom) or compounds (2+ different atoms combined) These all combine to make MATTER.

12. Understanding Elements on the Periodic Table (DRAW ME) Created by G.Baker www.thesciencequeen.net 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. Atomic Math: To figure out the number of Neutrons you: Subtract the ATOMIC NUMBER from the Atomic Mass (16-8=8)
