you may understand ionic bond as metal ion/ammonium ion(NH4+)/hydronium ion(H3O+) bonded with non-metal ion; and covalent bond as the bond formed beeen o or more non-metal atoms. 2011-06-23 18:38:53 补充： for the drawings ionic bond for example MgCl2 the diagram will b...
Ionic vs. Covalent Bonds The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur be...
metallic bonds 金属键，金属单质或者合金才会有。ionic bonds 离子键，阴阳离子间形成的，有阳离子和阴离子，一般是盐和碱中才有。covalent bonds 共价键，非金属元素之间的化学键，在离子化合物中、共价化合物中都有可能有。比如氢氧化钠中，钠离子与氢氧根离子是离子键，氢氧根里氢原子与氧原子是共价...
Although complex formation is an example of the linking together of species by the formation of covalent (but highly polar) bonds, the first systematic approach to the explanation of the properties of complexes was based on a model in which the effect of the ligands was treated as an essential...

An ionic bond is actually the extreme case of a polarcovalent bond, the latter resulting from unequal sharing of electrons rather than completeelectrontransfer. Ionic bonds typically form when the difference in theelectronegativitiesof the two atoms is great, while covalent bonds form when the elec...
PolarCovalentandIonicBondsIf we have two different elements that ahve an electronnegativity between 0.0 and 0.2, it is still considered a covalent bond. For example HAt = 2.2-2.1 = 0.1 We are only looking for the difference in values so we will alsways condier it a positive difference....
