Final answer:
The properties of an element that can be determined by looking at the periodic table include the atomic number, atomic mass, group number, and period number.
Step-by-step explanation:
By looking at the periodic table, you can determine several properties of an element. Here are some examples:
- The atomic number of an element is the number of protons in its nucleus. It is represented by a whole number on the periodic table.
- The atomic mass of an element is the average mass of its atoms. It is usually a decimal number and is also provided on the periodic table.
- The group number of an element represents its column on the periodic table. Elements in the same group have similar chemical properties.
- The period number of an element represents its row on the periodic table. Elements in the same period have the same number of electron shells.
These are just a few examples of properties that can be determined by looking at the periodic table. There are other properties as well, such as the element's symbol and name.
