N a mutual attraction between two atoms resulting from a redistribution of their outer electrons 化学键 → see also covalent bond, electrovalent bond, coordinate bond
She said: "Our match is made in heaven, there is a chemical bond between us."
她说:“我们是天作之合,我们之间有化学反应。”
This paper mainly discussed the important role of symmetrical principle on atom structure and chemical bond.
本文主要阐述了对称性原理在原子构造中和化学键中的重要作用。
A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion.
一个原子失掉一个电子来形成一个正离子,另一个原子得到一个电子来形成一个负离子的化学键。
So, in talking about covalent bonds, we should be able to still apply a more general definition of a chemical bond, which should tell us that the h 2 molecule is going to be lower in energy than if we looked at 2 separate hydrogen atom molecules.
那么,既然提到了共价键,我们应该还可以,给化学键下一个更普遍的定义,那就是告诉我们氢分子能量应该更低,与两个分开的氢的单原子分子相比。
So, we're going to start with talking about bonding, and any time we have a chemical bond, basically what we're talking about is having two atoms where the arrangement of their nuclei and their electrons are such that the bonded atoms results in a lower energythan for the separate atoms.
那么,下面我们将从成键开始讲起,无论什么时候我们有一个化学键,基本上我们所讨论的,都是如何安排两个原子的原子核的位置,与电子的位置使得成键的两个原子,最终比分开时的能量更低。
So the point is, this balance between energy thatyou could think of as say bond energies in chemical reactions, and entropy that you can think of in terms of disorder, how many different possible combinations or configurations of something wrong, will dictate where the equilibrium lies.
关键在于,这种能量与熵之间的平衡,确定了平衡的条件,在化学中能量涉及键能,而熵和无序有关,即有多少可能的不同组合或者形位,二者的平衡会告诉我们平衡态是什么样子。
