Faris Zuhair 9 Desember Konfigurasi Elektron dan Diagram Orbital. In the early days of quantum mechanicsit was proposed that electrons in different orbitals are further apart, so that electron—electron repulsion energy is hun. Satu kotak orbital berisi 2 elektron, satu tanda hind mengarah ke atas dan satu lagi mengarah ke bawah.

Aturan ini menyatakan bahwa: The first rule is especially important in chemistry, where it is often referred to simply as Hund’s Rule.

Hund’s rules – Wikipedia

Konfigurasi elektron dalam atom selain diungkapkan dengan diagram curah hujan, seringkali diungkapkan dalam diagram orbital. Lia Nurhakiki 5 Oktober Similarly for organic molecules, the same rule predicts that the first triplet state denoted by T 1 in photochemistry is lower than the first excited singlet state S 1which is generally correct.

The negative and positive signs refer only to the direction of the angular momentum, not the magnitude. 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.

Daffa Fatkhurrohman 13 September Mohon untuk berkenan pemilik materi hhe. Rank these terms associated with an electronic configuration of an atom based on energy via Hund’s rules: Unknown 16 Oktober Aturann reality, however, 1 D lies below aturaj G. However, there a problem with this rule.

Unknown 27 Agustus This rule deals with reducing the repulsion between electrons. Solution Possible states include: Berdasarkan diagram di atas dapat disusun urutan konfigurasi elektron sebagai berikut: Nomor kulit terbesarnya adalah 4 dalam 4s1 maka Cr terletak dalam periode 4.

This adds potential energy to them, so their energy level is higher.

Hund’s rules

Angga Damanik 10 Oktober However Hund’s rules should not be used to order states other than the lowest for a given configuration. Ryan Dritama 1 Oktober It can be shown that for full orbitals and suborbitals both the residual electrostatic energy repulsion between electrons and the spin—orbit interaction can only shift all the energy levels together. Lebih lengkapnya coba perhatikan tabel atjran bawah ini:.

Priyo Hartanto 4 Juni 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. Friedrich Hundseorang ahli fisika dari Jerman mengemukakan aturan pengisian elektron pada orbital yaitu:. Boleh ga materi ini saya copy ke aplikasi android yg mau saya buat?

Retrieved from ” hunnd Origin of Hund’s First Rule. Berlin Anggitasari 29 Agustus Sifat ini berhubungan erat dengan hibridisasi elektron. This rule considers the energy shifts due to spin—orbit coupling. As an example, consider the ground state of silicon.

Not to be confused with Hund’s cases. What matters is the relative momentum vectors of the various electrons in the system, and hence their sum total.

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

There’s a Coulomb repulsion between two electrons to put them in the same orbital a spin pairing energy often discussed in Crystal Field Theory. Pengisan elektron dalam kotak-kotak orbital menggunakan aturan Hund. Dalam setiap sub kulit mempunyai batasan elektron yang dapat diisikan yakni: Thus aturzn determining the ordering of energy levels in general only the outer valence electrons must be considered. So the expectations for Hund’s rules would be switched.
