3. Introduction
We are going to learn about the structure and the properties. The properties of a metal are related to bonds within the metal. A metallic bond is the attraction between a metal cation and the share electrons that surround it. The structure within a metal affects the properties of a metal. The two important properties of metals are the ability to conduct an electric current and malleability. Also we are going to learn about alloys that are a mixture of two or more elements. There are different types of alloys such as copper and steel.

4. Summary
The cations in a metal form a lattice that is held in place by strong metallic bonds between the cations and the surrounding valence electrons.
The mobility of electrons within a metal lattice explains some of the properties of metals.
Scientists can design alloys with specific properties by varying the types and amounts of elements in an alloy

5. Summary
The lattice in a metal is flexible compared to the rigid lattice in an ionic compound.
In a metal, cations are surrounded by shared valence electrons. If a metal is struck, the ions move to new positions, but the ions are still surrounded by electrons.

6. Conlclusion
In 6.4 it talked about light bulbs and about how people in the 1900's enjoyed the technology and tried to make it better. Also people tried to change the temperature of the bulb.
In section 6.4 its all about the metallic bonds and explaining the properties of metals. And the study of the electrons in the metals and the  reactions of metal with heat.

7. Questions
1.What are the forces that give a metal its structure as a solid?
2.How do metallic bonds produce some of the typical properties of metals?
3.How are the properties of alloys controlled?

8. Questions
4. What holds metal ions together in a metal lattice? 5. What characteristic of a metallic bond explains some of the properties of metals? 6. How can scientist design alloys with specific properties? 7. Explain why the metallic bonds in some metals are stronger than the bonds in other metals? 8. Why are metals good conductors of electric current? 9. How does adding carbon to steel make the steel harder and stronger? 10.
