Atomic Structure Review
1. What is the charge of an electron?
A proton?
A neutron?
2. What is the mass of an electron?
A proton?
A neutron?
3. An atom has 13 protons in its nucleus. Use a periodic table to find the following information about
that element:
Element Name:
Atomic Number:
Atomic Mass:
Most Common Mass Number:
Number of Electrons:
Draw a model of the element.
M-shell, and valence shell.
Number of Neutrons in Most Common Isotope:
Label the protons, neutrons, electrons, nucleus, K-shell, L-shell,
4. Draw atoms of the following two isotopes of lithium:
Lithium Isotope #1: Mass Number = 6
Lithium Isotope #2:
Mass Number = 7
5. Draw the following atom and ions of nitrogen (Atomic Number = 7). Use only protons and electrons
in your drawings – do not include neutrons.
Nitrogen Atom
Nitrogen Ion
Nitrogen Ion
(No Charge/Neutral)
(Positive +1 Charge)
(Negative -1 charge)
6. Make the following connections:
Isotope is connected to neutron because
Ion is connected to electron because
Atomic number is connected to proton because
Atomic mass is connected to isotope because
7. Choose from the following vocabulary words to make your own connections:
Atom
Nucleus
Atomic Number
Proton
Isotope
Positive Charge
Neutron
Ion
Negative Charge
Electron
Atomic Mass
No Charge (Neutral)
