polar covalent bond的意思是极性共价键。以下是关于极性共价键的详细解释：定义：极性共价键是一种化学键，它存在于两个不同电负性的原子之间。由于两个原子的电负性不同，共享的电子对会偏向电负性较大的原子，使得该原子带部分负电荷，而电负性较小的原子则带部分正电荷。特性：极性共价键的形成导致分子...

ionic, covalent, polar covalent, metallic, hydrogen 这五种Bond 键的强弱由大到小排列,急求,谢谢。 如题,谢谢。 一般来说,考虑到破坏化学键所消耗的能量,有以下顺序:ionic> polar covalent> covalent> hydrogen.而金属键metallic的强弱不好判断,相关理论解释也很
Pure vs. Polar Covalent Bonds If the atoms that form a covalent bond are identical, as in H2, Cl2, and other diatomic molecules, then the electrons in the bond must be shared equally. We refer to this as a pure covalent bond. Electrons shared in pure covalent bonds have an equal ...
一般来说，考虑到破坏化学键所消耗的能量，有以下顺序：ionic> polar covalent> covalent> hydrogen.而金属键metallic的强弱不好判断，相关理论解释也很负责，故一般不参与比较。
involved. In a covalent bond, the electronegativities of the two atoms are comparable. Conversely, hydrogen bond forms when the slightly positive hydrogen atom of a polar covalent bond forms an electrostatic link with the more electronegative atom of a polar covalent bond in the same or another...

If one atom is more electronegative than the other, it will pull harder on those shared electrons in the center, forming a polar bond. Apolar bondis a covalent bond in which the electrons are shared unequally. You can think of a polar covalent bond as being partway between a nonpolar coval...
Covalent bonds exist as nonpolar or polar-covalent bonds. In nonpolar covalent bonds, electrons are shared equally between identical atoms, as in the homonuclear bond in H2, the double C-C bond of ethylene (C2H4), the triple C-C bond of acetylene (C2H2), or the quadruple Re-Re bond in...
