The Lewis structure, also known as the electron dot structure, is a graphical representation of the electronic structure of a molecule. It is a useful tool for understanding the bonding and valence electrons of atoms within a molecule. The Lewis structure of sodium (Na) is relatively simple, consisting of a single electron in its outermost energy level.
To draw the Lewis structure of Na, we start by writing the symbol for sodium, which is Na. Then, we represent the single electron in the outermost energy level as a dot. The inner energy levels are not shown in the Lewis structure, as they are not relevant to the bonding of the atom.

In this representation, the dot represents the single valence electron of sodium. This electron is in the 3s orbital, which is the outermost energy level of the sodium atom.
One of the key aspects of the Lewis structure is that it helps to identify the number of valence electrons in an atom, which is crucial for understanding how atoms bond with each other. In the case of sodium, the single valence electron is easily removable, which is why sodium is highly reactive and tends to lose one electron to form a positive ion (Na+).
The Lewis structure of sodium can be compared to other elements in the periodic table, such as other alkali metals like lithium (Li) and potassium (K). These elements have a similar electron configuration, with a single electron in their outermost energy level, which makes them highly reactive and prone to losing one electron to form a positive ion.
In terms of its reactivity, sodium is highly prone to losing its single valence electron to form a positive ion. This is because the electron is in a high-energy state and is easily removable. As a result, sodium is highly reactive and tends to form compounds with other elements, such as chlorine (Cl) and oxygen (O).
In conclusion, the Lewis structure of sodium provides a useful representation of its electronic structure and reactivity. By understanding the arrangement of electrons in the atom, we can gain insights into its chemical properties and behavior.
What is the Lewis structure of sodium?
+The Lewis structure of sodium consists of a single electron in its outermost energy level, represented as Na•.
Why is sodium highly reactive?
+Sodium is highly reactive because it has a single valence electron that is easily removable, making it prone to losing one electron to form a positive ion (Na+).
What is the resulting compound when sodium reacts with chlorine?
+The resulting compound is sodium chloride (NaCl), which is more stable than the individual elements, as the electrons are arranged in a more stable configuration.
The Lewis structure is a fundamental concept in chemistry, and understanding it is crucial for grasping the electronic structure and reactivity of atoms and molecules. By applying the principles of the Lewis structure, we can gain insights into the behavior of highly reactive elements like sodium and predict their chemical properties and reactions.
