Basic Atomic Structure Review
Learning Target Addressed:
1.4 I can describe the charge and location of protons, neutrons, and electrons within the nucleus and shells of an atom.
The periodic table is, in many ways, the world’s greatest cheat sheet. The periodic table lists all of the elements (simple
substances that make up more complex materials) like gold, silver, tin, lead and mercury. It also provides lots of information
about these elements. The table was created a long time ago by a guy named Dmitri Mendeleev who, probably like you,
did not want to memorize tons of information. He organized the elements by mass. That worked pretty well to group
elements with similar properties together. Soon after a guy named Henry Moseley realized that each element has a
specific number of protons. We call this the atomic number of the element. When he rearranged the periodic table by
atomic number the elements grouped into columns with similar properties.
Questions:
1.
Who created the first periodic table?
2.
What is an element?
3.
What are the vertical (up and down) columns of the periodic table called? ___________________
4.
What are the horizontal (back and forth) rows of the periodic table called? __________________

What makes up each element?
Hour: ______
The parts that make up an element are called sub-atomic particles. There are three basic sub-atomic particles that we will
talk about in chemistry, they are called protons, neutrons and electrons. Each proton has one positive charge of
electricity (+1). Each electron has one negative charge of electricity (-1). Neutrons are neutral, which means they do not
have a charge.

What is a sub-atomic particle?
8.
What is the difference between a proton, a neutron and an electron?

1.7 I can describe the relationship between neutral atoms and ions of the same element.
Remember: The charge on an ion will involve a number and a sign. The number will always be the
number of electrons involved, e.g., loss of two electrons is +2. The sign will be positive if electrons
(negatives) are lost and negative if electrons are gained.

Practice with Isotopes
Hour: ______
Learning Target Addressed
1.8 I can describe the relationship between isotopes of the same element.
Isotopes are atoms of the same element with different masses (or weights) due to different numbers of neutrons
in their nuclei. All atoms of the same element must have the same number of protons (and thus the same number of electrons)
which is equal to the atomic number. However, atoms of the same element can have different numbers of neutrons and thus a
different mass number. The difference in mass does not influence the chemical behavior. Valence electrons are what determine
chemical behavior.
Hydrogen has three isotopes. The most abundant isotope is ordinary hydrogen-1. A second stable isotope is hydrogen-2 and the
third isotope is the radioactive hydrogen-3. The Bohr diagrams for the isotopes of hydrogen are shown below. Notice that
only the mass number and number of neutrons are different.

Practice Calculating Average Atomic Mass
Hour: ______
Learning Target Addressed: 1.11 I can calculate average atomic mass.
The atomic masses (or atomic weights) on the periodic table are the average of all the isotopes but it is not
a straight average. The atomic masses on the periodic table are the averages of all the isotopes based upon
abundance.
For example, consider element X:
60% mass 40 amu,
30% mass 42 amu
10% mass 44 amu,
then the periodic table mass would be calculated:
average mass based upon relative abundance
.60 x 40 amu = 24.0 amu
.30 x 42 amu = 12.6 amu
.10 x 44 amu = 4.4 amu
= 41.0 amu
