One way to visualize the arrangement of electrons in an atom is by using a Bohr diagram.
A Bohr diagram depicts the structure of an atom by showing the electron shells or energy levels surrounding the nucleus. In the case of chlorine, it has 17 electrons distributed across three energy levels: the first energy level can hold a maximum of 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 7 electrons.
In a Bohr diagram for chlorine, the nucleus is represented by a dot or a point in the center. The first energy level is closest to the nucleus and is depicted by a circle, while the second and third energy levels are shown as concentric circles that surround the first energy level. Each electron is represented by a dot that is positioned either on the energy level circle or within it, according to the number of electrons in that energy level.
Bohr Diagram for Chlorine
The Bohr diagram is a simplified model of the atomic structure that visualizes the arrangement of electrons in an atom. It was introduced by Niels Bohr in 1913 and is based on the concept that electrons orbit the nucleus in specific energy levels or shells.
Chlorine is a chemical element with the symbol Cl and atomic number 17. It belongs to the halogen group and is highly reactive. To draw the Bohr diagram for chlorine, we need to consider its atomic structure.
In the first energy level, there is a maximum of 2 electrons. In the second energy level, there can be a maximum of 8 electrons. The atomic number of chlorine is 17, indicating that it has 17 electrons. Therefore, the Bohr diagram for chlorine will have two energy levels.
- The first energy level will have 2 electrons, which will be represented by placing two dots or cross marks around the symbol Cl.
- The second energy level will have the remaining 15 electrons. These can be distributed in a way that maximizes stability and minimizes repulsion between electrons. One possible arrangement is to place 8 electrons in one direction and 7 electrons in the opposite direction.
The Bohr diagram for chlorine can be visualized as follows:
| Cl | • | • | • | • | • | • | • | • | • | • | • |
This arrangement of electrons follows the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a stable configuration with eight electrons in the outermost energy level.
In summary, the Bohr diagram for chlorine consists of two energy levels. The first energy level has 2 electrons, while the second energy level has 15 electrons arranged in a way that maximizes stability.

What is a Bohr Diagram?
A Bohr diagram is a simplified representation of an atom’s electron configuration, named after the Danish physicist Niels Bohr. It is a visual model that shows the placement of electrons in specific energy levels or electron shells around the atomic nucleus. The diagram consists of concentric circles representing these energy levels, with dots or symbols representing the electrons.
In a Bohr diagram, the first energy level is closest to the nucleus and can hold a maximum of 2 electrons. The second energy level can hold up to 8 electrons, and the third energy level can hold up to 18 electrons. The number of electrons in each energy level is determined by the atom’s atomic number, which corresponds to the number of protons in the nucleus.
The electrons in the Bohr diagram are placed in their respective energy levels based on certain rules. The first energy level is filled before moving on to the second energy level, and so on. Each energy level is filled before moving to the next level. The outermost energy level, also known as the valence shell, determines the atom’s chemical properties and reactivity.
The Bohr diagram provides a simple visual representation of the electron configuration, making it easier to understand and analyze the behavior of atoms. It is commonly used in chemistry to illustrate the arrangement of electrons in different elements and compounds.
