How do you find the number of electrons in chlorine?
In every stable atom the number of electrons is equal to the number of protons. Therefore, the number of electrons is equal to the number of protons in an chlorine atom. This means, that the number of electrons present in an chlorine atom is 17. Click to see full answer.
How many electrons are shared by chlorine?
There are two electrons shared by the two Cl atoms so there is a single bond between the Cl atoms. Each chlorine has 7 valence electrons plus the one it is sharing for a total of 8 valence electrons. So each Cl atom will have 8 valence electrons as a result of sharing. This is the rule of octet.
How many electrons does chlorine have in its Outter shell?
seven electrons. Each chlorine atom has seven electrons in its outer most shell. Each chlorine needs one more electron to gain a full outer shell and be stable. The chlorine on the left needs to share one electron to the chlorine on the right and the chlorine on the right needs to share one electron to the chlorine on the left.

How many electrons are in each shell?
The first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.
Chlorine (Cl) electron configuration through orbit
Scientist Niels Bohr was the first to give an idea of the atom’s orbit. He provided a model of the atom in 1913. The complete idea of the orbit is given there. The electrons of the atom revolve around the nucleus in a certain circular path. These circular paths are called orbit (shell). These orbits are expressed by n. [n = 1,2,3,4 .
Electron configuration of chlorine (Cl) through orbital
The German physicist Aufbau first proposed an idea of electron configuration through sub-orbits. The Aufbau method is to do electron configuration through the sub-energy level. These sub-orbitals are expressed by ‘l’.
How to write the orbital diagram for chlorine (Cl)?
To create an orbital diagram of an atom, you first need to know Hund’s principle and Pauli’s exclusion principle. Hund’s principle is that electrons in different orbitals with the same energy would be positioned in such a way that they could be in the unpaired state of maximum number and the spin of the unpaired electrons will be one-way.
Chlorine (Cl) excited state electron configuration
Atoms can jump from one orbital to another orbital by excited state. This is called quantum jump. Ground state electron configuration of chlorine is 1s 2 2s 2 2p 6 3s 2 3p 5. The valency of the element is determined by electron configuration in the excited state. The p-orbital has three sub-orbitals. The sub-orbitals are p x, p y, and p z.
Chloride ion (Cl –) electron configuration
After arranging the electrons, it is seen that the last shell of the chlorine (Cl) atom has seven electrons. In this case, the valence electrons of chlorine are seven. The elements that have 5, 6, or 7 electrons in the last shell receive the electrons in the last shell during bond formation.
