Atoms and the Atomic Theory

Atoms Remember that matter is anything that takes up space and has mass. All matter is made of atoms. Atoms are the smallest particle into which an element can be divided and still be the same substance.

Atomic Structure There are two basic parts in every atom: Electron Cloud or Shell Nucleus

Parts of an ATOM Charge Location Proton Positive (+) Nucleus or “Core” Neutron No Charge or neutral (0) Electron Negative (-) Electron Cloud

Subatomic Particles Electron Cloud: Electrons orbit the nucleus. Nucleus or “Core”: Protons and Neutrons are found in the nucleus.

Atomic Theory Because we can not see atoms, we use models to teach and learn about atoms. The atomic theory has changed over time as new technologies have become available. Remember: Scientific knowledge builds on past research and experimentation.

Atomic Theory Changes over time…
