非极性共价键和极性共价键
., electrically uniform—while those between unlike atoms are polar—i.e., oneatomis slightly negatively charged and the other is slightly positively charged. This partial ionic character of covalent bonds increases with the difference in the electronegativities of the two atoms.See alsoionic bond...
Many non-polar side chains may be incorporated into a single non-polar zone, creating a hydrophobic micro-environment that is quite different from the micro-environments in other parts of the protein molecule. In the case of metalloenzymes a further type of bond, the co-ordinate bond, needs...

covalent bond n. 1 a chemical bond that involves sharing a pair of electrons between atoms in a molecule网络释义 共价键 ...共价键(covalent bonds)是化学键的一种,两个或多个原子共同使用它们的外层电子,在理想情况下达到电子饱和的状态,由此组成比较稳定和坚固的化学结构叫做共... 相关网页 短语 ...
Polar Bonds Some relationships aren't equal. Some bonds aren't either. When the electrons of a molecular bond aren't shared equally by their atoms, it is called a polar bond. This type of bond leaves one of the atoms with a partial charge. Why are some atoms so possessive of electrons...
Covalent bonds may be polar or nonpolar depending on the electronegativity values of the two atoms involved in the bond. Electronegativity is the atom's ability to withdraw electrons toward itself. When there is a significant electronegativity difference between two atoms, a bond becomes polar since...
不是，dative covalent bond, 指的是共价键的成对电子由一方所提供，我们称为配位共价键。
