Chlorine (Cl2) is an element that exists in the form of a diatomic molecule—two chlorine atoms bound together. It is one of the most important halogens, being the scond most abundant halogen in the Earth’s atmosphere. Chlorine is a highly reactive non-metal and, consequently, has a wide range of uses in our everyday lives.
When chlorine forms an ionic bond with another element, it gains or loses electrons to become either positively charged (Cl+) or negatively charged (Cl-). The charge of an ion depends on the number of protons and electrons it contains—if there are more protons than electrons then the ion will be positively charged, and if there are more electrons than protons then the ion will be negatively charged.
In the case of chlorine, it gains one electron to become Cl-, forming what is known as a chloride ion. This is because it is more energetically efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons giving it a net negative (-1) charge.
The chloride ion plays an important role in human physiology as it helps regulate your body’s acid-base balance. In addition, chloride ions are also essential components in some industrial processes such as electroplating and metal finishing.
In summary, chlorine (Cl2) is a highly reactive non-metal that gains or loses electrons when forming ions. When chlorine gains one electron it becomes Cl-, forming what is known as a chloride ion with 17 protons, 17 neutrons and 18 electrons resulting in a net negative (-1) charge. The chloride ion plays an important role in human physiology and industrial processes.
Is Chlorine a Negative Ion?
No, Cl2 is not a negative ion. Cl2 is a diatomic molecule, meaning that it consists of two chlorine atoms bound together by covalent bonds. Since neither atom has more electrons than protons, the overall charge of the molecule is neutral.
Ions of Chlorine (Cl2)
Cl2 ions are chlorine atoms that have gained two electrons, forming a negatively charged ion with the chemical formula Cl−2. This ion is created when chlorine gas (Cl2) reacts with a positively charged ion, such as sodium or potassium. When this reaction occurs, the chlorine atom gains two electrons and forms Cl−2. Cl−2 ions are extremely reactive and form strong bonds with other molecules, making them important in many industrial processes such as water purification and bleaching.
The Charge of the Cl Ion
The chloride ion, Cl–, has one charge because it has gained one extra electron. Chlorine has an atomic number of 17, meaning it has 17 protons and 17 electrons in its neutral state. When chlorine gains an electron, it creates an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge. This is due to the fact that gaining one electron is more energy-efficient for chlorine than losing seven electrons. As such, chlorine tends to gain an electron and become a chloride ion with one negative charge.
Is a Chlorine Molecule Bonded by an Ionic Bond?
No, Cl2 is not an ionic bond. In an ionic bond, one atom will donate its electrons to another in order to create a transfer of charge between the two atoms. However, in Cl2, both chlorine atoms share and hold tightly onto their electrons, forming a covalent bond.
Cation or Anion: Is Cl2?
Chlorine (Cl2) is a cation due to its electron configuration and electronegativity. Chlorine has two outermost shell electrons, which form a single covalent bond with another chlorine atom, forming a molecule of Cl2. The two chlorine atoms share their outermost electrons, creating an even number of electrons overall. This puts chlorine in the category of an electropositive element, meaning that it carries a positive charge. As such, it forms a cation when it reacts with other elements.

The Charge of Chlorine
Chlorine has a charge of 2 because it requires two electrons to fill its outer shell and become stable. Chlorine is in Group 7 of the periodic table, meaning it has 7 electrons in its outer shell. As chlorine needs one more electron to form a full outer shell, it will form an ion with a negative charge. To gain stability and balance out the negative charge, chlorine must acquire two more electrons to form an ion with a charge of -2 (two negative charges).
Bond Type of Cl2
The bond type of Cl2 is a covalent bond. This type of bond occurs when two atoms share electrons in order to form a complete outer shell. In the case of Cl2, each chlorine atom contributes one electron to the shared pair, forming a single bond between the two chlorine atoms. The sharing of electrons ensures that both atoms have a full outer shell, resulting in a stable and strong bond.
The Chemical Composition of Cl2
Cl2, commonly known as chlorine gas, is a toxic, yellow-green gas composed of two chlorine atoms. It has a strong odor and is highly reactive, making it useful for bleaching and disinfecting. Chlorine gas is heavier than air and can accumulate in low-lying areas, causing severe respiratory irritation if inhaled. In addition to its uses in industry, Cl2 also plays an important role in the environment by helping to purify water supplies and reduce the growth of potentially harmful microorganisms.
Charge of Chloride Ion (Cl^1)
The charge of Cl (chlorine) is 1-. This means that the chloride ion always has a negative charge of 1. In other words, it carries one unit of negative electrical charge, which is why it is often referred to as a “negatively charged ion”. The charge of Cl can be determined by looking at its electron configuration; chlorine has seven electrons in its outer shell, so when it forms an ionic compound, it will lose one electron and become positively charged.
Number of Electrons in Cl- Ion
The ion Cl- has 18 electrons. It is composed of one chlorine atom with 17 protons and 17 electrons in its neutral form. When the atom loses one electron, it becomes an anion with a charge of -1 and 18 electrons.
Number of Bonds in CL2
Cl2 is a molecule composed of two chlorine atoms, and it is held together by one covalent bond. This bond is formed when the two chlorine atoms share an electron pair. This single covalent bond gives Cl2 its molecular stability and its characteristic shape. In short, Cl2 has one covalent bond.
Conclusion
In conclusion, chlorine (Cl2) is an atomic element made up of two chlorine atoms bonded together by covalent bonds. The element has 17 protons, 17 neutrons and 18 electrons, giving it a net negative charge of -1. This makes it a negatively charged ion called chloride. When chlorine gains one electron or when hydrogen chloride is dissolved in water or other polar solvents, the chlorine becomes a chloride ion and has a net negative charge of -1.
