What is electronic configuration of cl2?
2.1 Chlorine (Cl2) The electronic configuration of chlorine is: 1s2 2s2 2p6 3s2 3p5. Alternatively this can be written [Ne] 3s2 3p5 in other words the core electrons are 1s2 2s2 2p6 corresponding to the electronic configuration of the noble gas neon.
Does chlorine obey Hund’s rule?
The reason you count like this is to follow Hund’s Rule. This rule states that each orbital in a sub shell must be occupied by one electron before a second is added. If you were to just count the electrons from the bottom-up, you would get the 16th electron to be the 2nd electron in the second 3p sub shell.
How is Hunds rule calculated?
Hund’s first rule now states that the ground state term is 3P (triplet P), which has S = 1. The superscript 3 is the value of the multiplicity = 2S + 1 = 3.
What is the ground state electron configuration of the chloride ion Cl − CL −?
The electronic configuration for Cl- can, therefore, be designated as 1s22s22p63s23p6. Again, the electron configuration for the chloride ion is the same as that for Ca2+ and Argon.

How do you write the electron configuration for CL?
Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
What is Hunds rule quizlet?
Hund’s rule. every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. You just studied 3 terms!
Why is Hunds rule important?
Hund’s Rule can help predict the properties of atoms, as paired and unmated electrons have distinct properties (specifically with interactions with magnetic fields). When atoms come into contact with each other, the outer electrons of those atoms, or valence shell, initially interact.
What is Hunds rule simple?
Hund’s Rule. Hund’s rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
What is the electronic configuration of Cl 17?
Answer: The neutral atom chlorine (Z=17), for instance has 17 electrons. Therefore, its ground state electronic configuration can be written as 1s22s22p63s23p5.
What is the electronic configuration of 24?
Its electronic configuration in ground state is 1s2 2s2 2p6 3s2 3p6 4s1 3d5.
What is Hund’s rule for electron configuration?
Hund’s rule: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. Why chromium has electron configuration 4s1 3d5?
What is the ground state electron configuration of Cl in period 2?
Abbreviated ground state electron configuration Find noble gas in previous period – Cl is in period 3, Ne is the noble gas in period 2. => [Ne] The remaining 7 electrons will reside in 3s23p5. Abbreviated ground state electron configuration: [Ne]3s23p5
How does Hund’s rule work?
Briefly explain the working of Hund’s rule. As per its first rule, electrons before pairing up always enter an empty orbital. Since electrons are negatively charged particles they repel each other. When they occupy their orbitals they can easily minimize repulsion.
What is the Hunds rule of maximum multiplicity?
Hunds Rule of Maximum Multiplicity Hunds Rule of Maximum Multiplicity rule states that for a given electron configuration, the term with maximum multiplicity falls lowest in energy. According to this rule electron pairing in p, d and f orbitals cannot occur until each orbital of a given subshell contains one electron each or is singly occupied.
