The periodic table is a fundamental tool in chemistry that helps us understand the properties and behavior of elements. One of its key applications is in determining the electron configuration of an element, which is the arrangement of electrons in an atom. In this article, we will explore how to use the periodic table to fill in a table with the number of electrons in each energy level of a given element.

What is the Periodic Table?

The periodic table is a tabular arrangement of elements, organized by their atomic number (number of protons in the nucleus), electron configuration, and recurring chemical properties. The elements are listed in order of increasing atomic number (number of protons in the nucleus) and are grouped into rows called periods and columns called groups or families.

How to Use the Periodic Table to Determine Electron Configuration

To determine the electron configuration of an element, we need to know its atomic number. The atomic number is the number of protons in the nucleus of an atom, which determines the element's position in the periodic table. Once we know the atomic number, we can use the periodic table to determine the number of electrons in each energy level.

Energy Levels and Electron Shells

In an atom, electrons occupy specific energy levels or electron shells. The energy levels are designated by the principal quantum number (n), which can have values of 1, 2, 3, and so on. Each energy level has a specific capacity for electrons, which is determined by the number of orbitals available in that level.

Filling in the Table

Let's use the periodic table to fill in the table with the number of electrons in each energy level of a given element. We will use the element carbon (C) as an example.

Element n=1n = 1 level n=2n = 2 level n=3n = 3 level n=4n = 4 level
C

Step 1: Determine the Atomic Number of Carbon

The atomic number of carbon is 6. This means that a carbon atom has 6 protons in its nucleus.

Step 2: Determine the Electron Configuration of Carbon

To determine the electron configuration of carbon, we need to know the number of electrons in each energy level. We can use the periodic table to determine this information.

Energy Level Capacity Number of Electrons
n=1n = 1 2 2
n=2n = 2 8 4
n=3n = 3 18 2
n=4n = 4 32 0

Step 3: Fill in the Table

Now that we have the electron configuration of carbon, we can fill in the table.

Element n=1n = 1 level n=2n = 2 level n=3n = 3 level n=4n = 4 level
C 2 4 2 0

Conclusion

In this article, we have learned how to use the periodic table to fill in a table with the number of electrons in each energy level of a given element. We used the element carbon as an example and determined its electron configuration using the periodic table. By following these steps, we can determine the electron configuration of any element and fill in the table accordingly.
