| 1. | 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。 |
| 2. | 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。 |

| 8. | High temperatures are required , however , because the metal atoms grip the hydrogen with strong covalent bonds
然而，温度还是要够高，因为金属原子会以键结力强的共价键抓住氢。 |
| 9. | Considering when most of different atoms combine together , the covalent bond and the electrovalent bond are concomitant
考虑到大多数异类原子结合是采取共价结合与离子结合之间的过渡形式。 |
| 10. | In a covalent bond , two atoms share a pair of electrons , knitting together the respective electron orbitals . two electron pairs are shared in a double bond
在一个共价键中，两个原子共用一对紧密结合在各自电子轨道上的电子；在一个双键中，有两对电子共用。 |
