Kimyasal Bağ Türleri
Chemical bonding theories were pioneered by American chemist Gilbert N. Lewis. He developed a model called the Lewis model to explain the type…
Lewis Sembolleri ve Oktet Kuralı
Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis…
İyonik Bağ ve Elektron Transferi
Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its…
Born-Haber Döngüsü
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a…
Örgü Enerjisindeki Trendler İyon Boyutu ve Yükü
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a…
Kovalent Bağ ve Lewis Yapıları
Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual…
Elektronegatiflik
Whether a bond is nonpolar or polar covalent is determined by a property of the bonding atoms called electronegativity.  Electronegativity…
Bağ Polaritesi, Dipol Momenti ve Yüzde İyonik Karakter
The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected…
Moleküler Bileşiklerin ve Poliatomik İyonların Lewis Yapıları
To draw Lewis structures for complicated molecules and molecular ions, it is helpful to follow a step-by-step procedure as outlined: Determine the…
Rezonans
The Lewis structure of a nitrite anion (NO2−) may actually be drawn in two different ways, distinguished by the locations of the N-O and N=O…
Formal Yükler
In some cases, there are seemingly more than one valid Lewis structures for molecules and polyatomic ions. The concept of formal charges can be used…
Oktet Kuralının İstisnaları
Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three…
Bağ Enerjileri ve Bağ Uzunlukları
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break…
Metallerde Bağlanma
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the…
Polyatomic radikal katyonlar güçlü alanlı adyabatik iyonlaşma ile Ultrafast titreşim Coherences ölçümü
We present a pump-probe method for preparing vibrational coherences in polyatomic radical cations and probing their ultrafast dynamics. By shifting…
Oda sıcaklığında karbon Nanosheets hazırlanması
Amphiphilic molecules equipped with a reactive, carbon-rich "oligoyne" segment consisting of conjugated carbon-carbon triple bonds self-assemble into…
