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...
Please notice that: Covalent bond can be applied to both metals and non-metals (e.g. polyatomic ions)一个化合物中 由金属及非金属组成 如 NaCl (氯化钠) 就系ionic covalent就系由非金属组成 如 CO2(二氧化碳) 咁你明啦- - 画图的话呢 书上就有ga啦。
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...

Covalent Bond vs. Ionic Bond Covalent and ionic bonds are the two types of chemical bonds between atoms.A covalent bond is a chemical bond between atoms that occurs when they share one or more electrons. Since neither atom is strong enough to attract an electron from the other, they share...
3.1 Covalent and Ionic Bonds Two major types of chemical bonds exist (i.e. covalent and ionic). The covalent bond is defined as a region of relatively high electron density between nuclei that arises, at least partly, from the sharing of electrons and produces an attractive force and characte...
Covalent bonds are formed by equal sharing of electrons. Understand Covalent Bonding with Properties, Types - Polar, Non-Polar bonds, Difference between Covalent and Ionic Bonds, Examples
Let’s Look….. 2 lithium atoms are needed to complete the ionic bond! -2 Charge +1 Charge +1 Charge Question? How would you write the chemical formula? +1 Charge +1 Charge -2 Charge Li 2 O Let’s Practice….. Directions: Show the ionic bond and charge formed between the fol ...
