Faris Zuhair 9 Desember What matters is the relative momentum vectors of the various electrons in the system, and hence their sum total. This adds potential energy to them, so their energy level is higher.

However, there a problem with this rule. Latifah Fajrin 3 Desember By convention we usually draw the first electron in each orbital as “up” positive spin. Not to be confused with Hund’s cases. All things being equal, the total spin angular momentum of the 1 electron system would be opposite in sign to whatever the total spin angular momentum of the 5 electron system is.

Berdasarkan diagram di atas dapat disusun urutan konfigurasi elektron sebagai berikut: Here the symbols S, P, D, F, and G indicate that the total orbital angular momentum quantum number nund values 0, 1, 2, 3 and 4, respectively, analogous aaturan the nomenclature for naming atomic orbitals.

Unknown 16 Oktober In the latter case the repulsive force increases, which separates electrons. Dalam penulisan konfigurasi elektron dan diagram orbital perlu berlandaskan pada tiga prinsip utama yaitu prinsip aufbau, aturan Hund dan aturan penuh setengah penuh. Coba perhatikan contoh diagram elektron di bawah ini, khususnya pada bagian atjran. This page was last edited on 10 Octoberat So is the spin direction, incidentally.

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. Taking as an example – the three p-orbitals. From Wikipedia, the free encyclopedia. Lia Nurhakiki 5 Oktober Untuk menentukan letak periode suatu unsur relatif mudah.

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

For silicon there is only one triplet term, so the second rule is not required. Ryan Dritama 1 Oktober 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. In what order should they be filled?

Electrons tend to minimize repulsion by occupying their own orbitals, rather than sharing an orbital with another electron. Angga Damanik 10 Oktober The first rule is especially important in chemistry, where it is often referred to simply as Hund’s Rule.

Solution Possible states include: Berlin Anggitasari 29 Agustus Option Hastagemily 29 Oktober Hund’s rules work best for the determination of the ground state of an atom or molecule. Certainly, 1s orbitals should be filled before 2s orbitals, because the 1s orbitals have a lower value of n, and thus a lower energy.

This would be because the spin angular momentum of a single hole would be opposite in sign compared to the spin angular momentum of a single electron. Dalam setiap sub kulit mempunyai batasan elektron yang dapat diisikan yakni: As an example, consider the ground state of silicon. Sasa Ismi 30 September Lebih lengkapnya coba perhatikan tabel di bawah ini:. Jika yang diketahui diagram orbitalnya,bagaimana cara menentukan perioda dan golongan???
