| 1. | In covalent bonding, atoms share electrons . 在共价键联中,原子共有电子。 |
| 2. | The simplest covalently bonded molecule is formed from two hydrogen atoms . 最简单的共价键分子由两个氢原子组成。 |
| 3. | Crystals may be classified as either ionic or covalent by analogy with molecules . 与分子的情况一样,晶体也可以分为离子键型和共价键型。 |
| 4. | Further study is needed before the origin of the covalent bond can be considered a settled question . 需进一步深入研究方能解决共价键的起源问题。 |
| 5. | Both ionic and covalent bonds arise from the tendency of atoms to attain this stable configuration of electrons . 离子键和共价键都是由于原子要达到这个稳定电子构型而形成的。 |
| 6. | They stick together by a strong bonding called covalent bond 它们以一种很强的键- -共价键,黏合在一起 |
| 7. | O . they stick together by a strong bonding called covalent bond O的原因.它们以一种很强的键-共价键,黏合在一起 |
| 8. | Ceramics primarily have ionic bonds , but covalent bonding is also present 陶瓷初始状态是受离子束缚的,但是还是有共价键结构的。 |
| 9. | It is often represented by a single line between the symbols of the two atoms that are bonded together 通常用两个原子符号之间的连线来表示共价键的形成。 |
| 10. | Covalent bond a chemical bond in which one or more pairs of electrons are shared between two atoms 共价键:一般指两个原子接合时,通过形成共有电子对而产生的化学键。 |
