4. An atom refresher Matter is anything that takes up space and has mass. All matter is made of atoms Atoms are the building blocks of matter, sort of how bricks are the building blocks of houses.

6. 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 in the electron cloud. An atom refresher Highlight Atomic Structure Notes Pair and Share

8. From the highlighted material create a chart in your ISN listing the characteristics of the three subatomic particles. ProtonsNeutronsElectrons

9. What are elements? Elements are the alphabet to the language of molecules. To make molecules, you must have elements. Elements are made of atoms. While the atoms may have different masses and organization, they are all built in the same way.

10. The nucleus of the atom houses the protons and neutrons. Nucleus = Center Protons – Positive Represented by a + sign + Neutron no Charge Represented by a “o” or left blank o

11. Electrons a special place…. Electrons exist in a cloud surrounding the nucleus. Only so many electrons can be in any certain shell, orbital, energy level. Now Electrons

13. More about Elements.. Elements 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 chemistry. The periodic table tells us several things…

14. Periodic Table 8 O Oxygen 16 Atomic Number: Number of protons and it is also the number of electrons in a neutral atom of an element. Element’s Symbol: An abbreviation for the element. Element’s Name Atomic Mass: Number of protons + neutrons. Periodic Table is our next unit

15. There are two models of the atom we will be using in class: Bohr Model Lewis Dot Diagram Coming Soon to a Theatre near you Laboratory
