Summary Ionic compounds contain ionic bonds formed by the attraction of oppositely charged ions. Ions in a ionic compound are arranged in repeating patterns known as a crystal lattice. Ionic compounds properties are related to ionic bond strength. Ionic compounds are electrolytes; they conduct an ele...

Formation of Ionic Compounds Compounds composed of cations and anions are called ionic compounds They. Essential Questions: ...
2. Describe how ionic bonds are formed. Chemists have concluded that atoms are especially stable if they have eight electrons in their outermost shell. This useful rule of thumb is called the octet rule, and it is a key to understanding why compounds form. These elements—helium, neon, argon...

Have you ever wondered what happens when metals and non-metals react? They form ionic bonds which form ionic compounds. An ionic bond is the electrostatic force of attraction between two oppositely charged ions. Let’s find out more about it. Suggested Videos Introduction to Metals Introduction ...
The properties of ionic compounds shed some light on the nature of ionic bonds. Ionic solids exhibit a crystalline structure and tend to be rigid and brittle; they also tend to have high melting and boiling points, which suggests that ionic bonds are very strong. Ionic solids are also poor ...
Ionic Bonds and FormulasRichard Parsons
metallic bonds，金属键：在金属晶体中，自由电子作穿梭运动，它不专属于某个金属原子而为整个金属晶体所共有。这些自由电子与全部金属离子相互作用，从而形成某种结合，这种作用称为金属键。 所有的金属单质，铁、铜、银、等等原子都通过是金属键结合的。ionic bonds，离子键：指离子之间的相互作用，大...
