A bond’s strength describes how strongly each atom is joined to another atom, and therefore how much energy is required to break the bond between the two atoms. In this section, you will learn about the bond strength of covalent bonds, and then compare that to the strength of ionic bonds...
you may understand ionic bond as metal ion/ammonium ion(NH4+)/hydronium ion(H3O+) bonded with non-metal ion; and covalent bond as the bond formed beeen o or more non-metal atoms. 2011-06-23 18:38:53 补充： for the drawings ionic bond for example MgCl2 the diagram will b...

Lewis Diagrams of covalent bonds Lewis diagrams of covalent bonds are also very easy. Like Bohr diagrams, valence electrons are drawn to show sharing of electrons. All atoms wish to have a full valence shell (1st orbit=2 e-, 2nd=8e-) The shared pairs of electrons are usually drawn as ...
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...

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...
