Nama : Rafif Rizmawan NRP : TUGAS KIMIA REKAYASA | Fariz Nur Fitriawan –

Konfigurasi elektron dalam atom selain diungkapkan dengan diagram curah hujan, seringkali diungkapkan dalam diagram orbital. For silicon there is only one triplet term, so the second rule is not required. Azas Aufbau menyatakan jund The electronic configuration of Si is 1s 2 2s 2 2p 6 3s 2 3p 2 see spectroscopic notation.

According to the first rule, electrons always enter an empty orbital before they pair up. Sedangkan untuk menentukan golongan menggunakan tabel. By convention we usually draw the first electron in each orbital as “up” positive spin. Friedrich Hundseorang ahli fisika dari Jerman mengemukakan zturan pengisian elektron pada orbital yaitu:.

Media Belajar Online: Konfigurasi Elektron dan Diagram Orbital

Daffa Fatkhurrohman 13 September The orbitals of the subshell are each occupied singly with electrons of parallel spin before double occupation occurs. Mohon untuk berkenan pemilik materi hhe. Hund’s First Rule Maximize Spin Multiplicity According to the first rule, electrons always enter an empty orbital before they pair up. What is the term zturan lowest energy state for the following atoms and ions. This adds potential energy to them, so their energy level is higher. Buah Kasih 23 September The rules assume that the repulsion between the outer electrons is much greater than the spin—orbit interaction, which is in turn huund than any other remaining interactions.


This rule deals with reducing the repulsion between electrons. From Wikipedia, the free encyclopedia.

Rank these terms associated with an electronic configuration of an atom based on energy via Hund’s rules:. Thus when determining the hnud of energy levels in general only the outer valence electrons must be considered. Aufa Ikhsan 13 Oktober Hund’s first rule states that the lowest energy atomic state is the one that maximizes the total spin quantum number for the electrons in the open subshell.

A situation with 1 electron and 5 electrons are functionally similar, except that one has a single electron and one has a single hole.

You can kind of see this if you draw out all the microstates of the 1-electron and 5-electron configurations: Priyo Hartanto 4 Juni Hund’s rules work best for the determination of the ground state of an atom or molecule. Bila subkulit terakhirnya pada s atau p maka digolongkan dalam golongan A utama sedangkan bila subkulit terakhirnya pada d maka digolongkan dalam golongan B transisi.

Hund’s rules

Nomor kulit terbesarnya adalah 4 dalam 4s1 maka Cr terletak dalam periode 4. Unknown 15 Oktober Hund’s rule of maximum multiplicity. However, there a problem with this rule.

Chandra Pittza 10 Juli Retrieved from ” https: Unknown 10 September Berarti walaupun penulisan 3d6 4s2 untuk fe misalnya, itu bil. Coba perhatikan contoh diagram elektron di bawah ini, khususnya pada bagian akhirnya:. Unknown 27 Agustus There’s a Aturn repulsion between two electrons to hind them in the same orbital a spin pairing energy often discussed in Crystal Field Atran.


They are also fairly reliable with occasional failures for the determination of the lowest state of a given excited electronic configuration.

Aturan ini menyatakan bahwa: Here the symbols S, P, D, F, and G indicate that the total orbital angular momentum quantum number has values 0, 1, 2, 3 and 4, respectively, analogous to the nomenclature for naming atomic orbitals. The direction is furthermore arbitrary except in, say, a magnetic or electric field.

8.10: Hund’s Rules Determine the Term Symbols of the Ground Electronic States

A long time ago someone offering a reasonably simple explanation related to the fact that when the shell is more than half full, it’s easier to visualize the hynd as an interaction between the spin and orbital momenta of holes rather than electrons, in which case the energetic stabilization term is reversed in sign. Faris Zuhair 9 Desember What about the three different 2p orbitals?

Furthermore, quantum-mechanical calculations have shown that hnud electrons in singly occupied orbitals are less effectively screened or shielded from the nucleus. This would be because the spin angular momentum of a single hole would be opposite in sign compared to the spin hhnd momentum of a single electron. Jika yang diketahui diagram orbitalnya,bagaimana cara menentukan perioda dan golongan???
