화학결합: 기본 개념

화학 결합 종류
화학 결합 종류
Chemical bonding theories were pioneered by American chemist Gilbert N. Lewis. He developed a model called the Lewis model to explain the type and ...

루이스 기호와 옥텟 규칙
Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a ...
이온결합과 전자 이동
이온결합과 전자 이동
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 valence ...
보른-하버 순환
보른-하버 순환
Lattice Energy  An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a ...
격자에너지 경향: 이온 크기와 전하
격자에너지 경향: 이온 크기와 전하
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure ...
공유결합과 루이스 구조
공유결합과 루이스 구조
Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual ...
전기음성도
전기음성도
Whether a bond is nonpolar or polar covalent is determined by a property of the bonding atoms called electronegativity.  Electronegativity values of ...
결합 극성, 쌍극자 모멘트, 퍼센트 이온성
결합 극성, 쌍극자 모멘트, 퍼센트 이온성
Bond Polarity The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be ...
분자 화합물과 다원자 이온의 루이스 구조
분자 화합물과 다원자 이온의 루이스 구조
To draw Lewis structures for complicated molecules and molecular ions, it is helpful to follow a step-by-step procedure as outlined: Determine the ...
공명

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 ...
형식전하
형식전하
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 to ...
옥텟 규칙의 예외
옥텟 규칙의 예외
Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories: ...
결합에너지와 결합길이
결합에너지와 결합길이
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break it, ...
금속의 결합
금속의 결합
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the ...
