Chapter 4<br />
Unit 2<br />
Atomic Structure<br />
The students will learn what makes up atoms and how are<br />
atoms of one element different from atoms of another element.<br />
Explore the scientific theory of atoms (also known as atomic theory) by describing<br />
changes in the atomic model over time and why those changes were necessitated by<br />
experimental evidence.<br />
Students will be able to draw/identify each atomic model.<br />
Students will be able to compare/contrast the different atomic models.<br />
Students will be able to describe how results of experimental evidence caused the atomic<br />
model to change.<br />
proton<br />
nucleus<br />
electron<br />
electron cloud<br />
neutron<br />
Explore the scientific theory of atoms (also known as atomic theory) by describing the<br />
structure of atoms in terms of protons, neutrons and electrons, and differentiate among<br />
these particles in terms of their mass, electrical charges and locations within the atom.<br />
<br />
Students will compare/contrast the characteristics of subatomic particles.<br />
atomic number<br />
mass number<br />
isotope<br />
Chapter 5<br />
atomic mass unit (amu)<br />
atomic mass<br />
Electrons in Atoms<br />
The students will be able to describe the arrangement of<br />
electrons in atoms and predict what will happen when<br />
electrons in atoms absorb or release energy.<br />
Describe the quantization of energy at the atomic level.<br />
Students will participate in activities to view emission spectrums using a diffraction grating or a<br />
spectroscope.<br />
Students will be able to explain how the spectrum lines relate to electron motion.<br />
energy level<br />
atomic orbital<br />
quantum mechanical model<br />
