Pengisan elektron dalam kotak-kotak orbital menggunakan aturan Hund. The direction is furthermore arbitrary except in, say, a magnetic or electric field. Ungkapan yang kedua akan bermanfaat dalam menentukan bentuk molekul dan teori hibridisasi.

Mohon untuk berkenan pemilik materi hhe.

Ryan Dritama 1 Oktober Similarly for organic molecules, the same rule predicts that the first aturn state denoted by T 1 in photochemistry is lower than the first excited singlet state S 1which is generally correct. Nomor kulit terbesarnya adalah 4 dalam 4s1 maka Cr terletak dalam periode 4. So the expectations for Hund’s rules would be switched.

Option Hastagemily 29 Oktober This is occasionally called the “bus seat rule” since it is analogous to the behaviour of bus passengers who tend to occupy all double seats singly before double occupation occurs.

Hund’s rules – Wikipedia

By convention we usually draw the first electron in each orbital as “up” positive spin. Unknown 2 Oktober The first rule is especially important in atuan, where it is often referred to simply as Hund’s Rule. Berarti walaupun penulisan 3d6 4s2 untuk fe misalnya, itu bil.


This rule considers the energy shifts due to spin—orbit coupling. Muhammad Haidar 15 September In atomic physicsHund’s rules refers to a set of rules that German physicist Friedrich Hund zturan aroundwhich are used to determine the term symbol that corresponds to the ground state of a multi- electron atom. However, there a problem with this rule.

From Wikipedia, the free encyclopedia. Berdasarkan diagram di atas dapat disusun urutan konfigurasi elektron sebagai berikut: These rules specify in a simple way how usual energy interactions determine aturaj term includes the ground state. The exchange energy which is favorable increases with the number of possible exchanges between electrons with the same spin and energy.

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

What matters is the relative momentum vectors of the various electrons in the system, and hence their sum total. Satu kotak orbital berisi 2 elektron, satu tanda panah mengarah ke atas dan satu lagi mengarah ke bawah.

You can kind of see this if you draw out all the microstates of the 1-electron and 5-electron configurations: Dalam setiap sub kulit mempunyai batasan elektron yang dapat diisikan yakni: Chandra Pittza 10 Juli Lebih lengkapnya coba perhatikan tabel di bawah ini:.

It can be shown that for full orbitals and suborbitals both the residual electrostatic energy repulsion between electrons and the hjnd interaction can only shift all the energy levels together. This page was last edited on 10 Octoberat Wturan Hund’s rules should not be used to order states other than the lowest for a given configuration.


Angga Damanik 10 Oktober Origin of Hund’s First Rule. This adds potential atuuran to them, so their energy level is higher. So is the spin direction, incidentally.

However we could just as easily draw it “down”. The electronic configuration of Si is 1s 2 2s 2 2p hubd 3s 2 3p 2 see spectroscopic notation. Electrons are negatively charged and, as a result, they repel each other. Lia Nurhakiki 5 Oktober What matters is the total scalar angular momentum, not the direction. This is referred to as the LS coupling regime. What is the term of lowest energy state? Jika yang diketahui diagram orbitalnya,bagaimana cara menentukan perioda dan golongan???

Untuk menentukan letak periode suatu unsur relatif mudah. The rules assume that the repulsion between the outer electrons is much greater than the spin—orbit interaction, which is in turn stronger than any other remaining interactions. The orbitals of the subshell are each occupied singly with electrons of parallel aturqn before double occupation occurs.
