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.

So the ground state is from this more narrowed list: As an example, consider the ground state hud silicon. Angga Damanik 10 Oktober Banyaknya kotak ditentukan berdasarkan bilangan kuantum magnetik, yaitu:. However we could just as easily draw it “down”. Pengisan elektron dalam kotak-kotak orbital menggunakan aturan Hund. This is referred to as the LS coupling regime. aturaj

Hund’s rules – Wikipedia

What is the term of lowest energy state for the following atoms and ions. So the expectations for Hund’s rules would be switched. The first rule is especially important in chemistry, where it is often referred to simply as Hund’s Rule.

It can be understood from the classical picture that if all electrons are orbiting in the same direction higher orbital angular momentum they meet less often than if some of them orbit in opposite directions. 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. Due to the Pauli exclusion principletwo electrons cannot share the same set of quantum numbers within the same system; therefore, there is room for only two electrons in each spatial orbital.

In reality, however, 1 D lies below 1 G.

Hund’s rules

These rules specify in atuuran simple way how usual energy interactions determine which term includes the ground state. However Hund’s rules should not be used to order states other than the lowest for a given configuration. Two different physical explanations have been given [4] for the increased stability of high multiplicity states. This rule considers the energy shifts due to spin—orbit coupling.

Untuk menentukan letak periode suatu unsur relatif mudah. Aturan ini menyatakan bahwa: Sasa Atyran 30 September Jika yang diketahui diagram orbitalnya,bagaimana cara menentukan perioda dan golongan???

Chandra Pittza 10 Juli You can kind of see this if you draw out all the microstates of the 1-electron and 5-electron configurations: This page was last edited on 10 Octoberat Unknown 15 Oktober By convention we usually hune the first electron in each orbital as “up” positive spin.

However, there’s also a quantum mechanical effect. 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. Boleh ga materi ini saya copy ke aplikasi android yg mau saya buat?

The rules assume that the repulsion between the outer electrons is much greater than the spin—orbit interaction, which athran in turn stronger than any other remaining interactions. Berdasarkan diagram di atas dapat disusun urutan konfigurasi elektron sebagai berikut: Muhammad Haidar 15 September Lebih lengkapnya coba perhatikan tabel di bawah ini:. Berlin Anggitasari 29 Agustus Dalam setiap sub kulit mempunyai batasan elektron yang dapat diisikan yakni: So is the spin direction, incidentally.

By using zturan site, you agree to the Terms of Use wturan Privacy Policy. Thus when determining the ordering of energy levels in general only the outer valence electrons must be considered. Electrons tend to minimize repulsion by occupying their own orbitals, rather than sharing an orbital with another electron. Retrieved from ” https: Rank these terms associated with an electronic configuration of an atom based on energy via Hund’s rules: Aruran to the first rule, electrons always enter an empty orbital before they pair up.

Buah Kasih 23 September This adds potential energy to them, so their energy level is higher.

Coba perhatikan contoh diagram elektron di bawah ini, khususnya pada bagian akhirnya:. 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.

This rule deals with reducing the repulsion between electrons.
