UNIT 4.1-Atomic Structure and Properties
Student Progress Monitoring (SPM)
1.
Atomic Structure- 8.5 A
 We will describe the masses, electrical charges and locations of protons, neutrons and
electrons.
Vocab:
Electron
Electrical charge
Subatomic particle
Proton
Electron cloud
Nucleus
Neutron
Atomic mass number
Neutral
Atom
Atomic number
Positive/negative
Questions:
A. Describe the locations and electrical charges of a proton, electron, and neutron.
B. Explain the similarities and differences of the masses of the subatomic particles.
C. How can you determine the number of protons, neutrons and electrons in an atom using the
Periodic Table?
D. What is the electrical charge of an atom’s nucleus and why? What is the electrical charge of an
atom’s electron cloud and why?
2.
Protons and Valence Electrons 8.5B
• We will identify that protons are an atom’s identity and that valence electrons determine
reactivity and other chemical properties.
Vocab:
Valence Electron
Reactivity
Proton
Questions:
A.
B.
C.
D.
How is the identity of an atom determined?
Define valence electron and explain the importance of them.
How many electrons can be held in the 1st 3 energy levels (shells)
Define reactivity and what determines an element’s reactivity.
