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。
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

Considerably lower dielectric constants, as compared to HF, also mean that these compounds do not, in general, solubilize ionic compounds very readily. Nevertheless, work with HCl has indicated that this solvent system provides a convenient medium for the preparation of a number of chlorinated or ...

In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) where it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+. The H+ cation is simply a proton (symbol p) but its behavior in aqueous solutions and ...
