covalent bond,ionic bond,metallic bond请说明他们有什么不同? 答案 分别是共价键、离子键、金属键的意思.共价键是化学键的一种,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价键.与离子键不同的是进入共价键的原子...相关推荐 1covalent bond,i...
the atoms are covalently bonded (further divided to polar and non-polar) while if the difference is larger than 2 the atoms are ionically bonded But for your level you may understand ionic bond as metal ion/ammonium ion(NH4+)/hydronium ion(H3O+) bonded with non-metal ion; and...
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...

分别是共价键、离子键、金属键的意思。共价键是化学键的一种,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价键。与离子键不同的是进入共价键的原子向外不显示电性,因为它们并没有获得或损失电子。共价键的强度比氢键要强,与离子键...

...所以大家都差不多 参考: 差不多...先生说的 First Ionic bond is held by metal cations and non-metal anions which me it is held by metal and non-metal.But covalent bond is held beeen the nucleii and the outermost electrons by onlt non-metal.Is it clear?
A molecule or compound is made when two or more atoms form a chemical bond, linking them together. The two types of bonds are ionic bonds and covalent bonds. The distinction between them has to do with how equally the atoms participating in the bond share their electrons. For example, ioni...
