Electrons are the basis of our understanding of the chemical world. They are the building blocks that organize and control the behavior of atoms and molecules. Knowing the electron configuration of an element can help us understand its chemical properties and reactivity.
But what exactly is an electron configuration? It is a standard notation used to describe how electrons are distributed in an atom’s orbitals. Each orbital is identified by its energy level and the number of electrons it contains. These are written as superscripts in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1.
However, writing electron configurations for elements with a large atomic number can get quite lengthy. In order to simplify this process, scientists use the orbital-filling chart in Figure 5.9. This chart indicates the order in which the orbitals should be filled. For example, the electron configuration of boron is 1s22s22p6 3s2 3p4, which is derived from the orbital-filling chart.
Table 5.2 shows the electron configurations of the elements with atomic numbers 1 through 18. Knowing the electron configuration of an element can give us valuable insights into its properties and behavior. For example, the electron configuration of lithium is 1s22s1, which indicates that it has only one electron in its outer shell and is highly reactive.
In this article, we will explore what electron configurations are and how they are determined. We will also look at the orbital-filling chart and how it can be used to determine the electron configuration of an element. Finally, we will discuss the significance of knowing the electron configuration of an element and how it can help us understand its properties and reactivity.

When it comes to determining the electron configuration of an element, it can be a bit tricky. But by following the orbital-filling chart in Figure 5.9, you can easily figure out the electron configuration of any element. For instance, the electron configuration of boron is:

Li: 1s22s1
Similarly, boron (atomic number 5) has five electrons. Four electrons fill both the 1s and 2s orbitals. The fifth electron is added to a 2p orbital, the sublevel next higher in energy (Figure 5.9). Therefore, the electron configuration of boron is:
B: 1s22s22p1
Now let’s take a look at the electron configuration of fluorine (atomic number 9). The electron configuration of fluorine is:
F: 1s22s22p63s23p5
Now let’s look at the electron configuration of an element with an atomic number greater than 18. For example, let’s consider bromine (atomic number 35). The electron configuration of bromine is:
Br: 1s22s22p63s23p64s23d104p65s24d105p5
By following the orbital-filling chart in Figure 5.9, you can easily determine the electron configuration of any element. Now that you know the basics of electron configurations, let’s answer the question: Which element has the electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 4?
The answer is boron (atomic number 5). Its electron configuration is:
B: 1s22s22p1

The electrons fill the orbitals in pairs until the outermost energy level is filled with eight electrons.
What is Noble Gas Shorthand?
Noble gas shorthand is a way of writing the electron configuration of an element without writing out the entire configuration. It involves writing the symbol for the noble gas before the element symbol and then adding the extra information. For example, the electron configuration of radon can be written as [Rn] 5f14 6d10 7s2 7p6. This shorthand can be used to save room when writing out electron configurations.
