1. An ionic bond is characterized by the transfer of an electron from one atom to the other .
   離子鍵的特點是一個電子可以從一個原子轉(zhuǎn)移到另一個原子。
2. Ceramics primarily have ionic bonds , but covalent bonding is also present
   陶瓷初始狀態(tài)是受離子束縛的，但是還是有共價鍵結(jié)構(gòu)的。
3. The chains are held together by ionic bonds , whereas individual silica tetrahedrals bond together covalently
   這些鏈狀四面體組織由離子鍵束縛，而一個個單獨的硅四面體卻以共價鍵結(jié)合在一起。
4. In recent years researchers have achieved better performance with compounds such as lithium borohydride , in which the metal atoms form weaker , ionic bonds with groups containing several hydrogen atoms
   近年來，研究人員已經(jīng)制作出效能更佳的復(fù)合物，例如硼氫化鋰，在這種金屬氫化物中，金屬原子與氫原子團（由數(shù)個氫原子組成）之間，是以較弱的離子鍵鍵結(jié)。
5. Montmorillonite ( mmt ) clay is an important class of lamellar inorganic compounds , contains negatively charged layered silicates , which are bonded with metal cations such as na + or ca2 + by ionic bonding . whose interlayer spacing can be modified by cation exchange . when the mmt is exchanged with cations , its inner layer spacing becomes large enough to be penetrated by a monomer
   蒙脫土( montmorillonite ， mmt )是一種天然礦物，具有層狀結(jié)構(gòu)，層間靠吸附陽離子如na ~ + 、 ca ~ ( 2 + ) 、 mg ~ ( 2 + )等來維持電荷平衡，這些離子可與其它陽離子進行交換，使有機單體分子進入層間，聚合后即可形成有機無機納米復(fù)合材料。
