Metals all have a ____ metallic structure. This means that the metal atoms are ____ packed together in a regular repeating 3-____ pattern. The ____ electrons in the outer shell of each metal atom are released leaving behind ____ ions. These electrons are ____ and free to move around between the positive ions, which is why metals are good ____ of heat and ____. In a metal's structure the positive ____ ions are strongly attracted to the negative delocalised ____. This means the metallic bonds between the atoms are very ____ and require a lot of ____ to break them. This results in a ____ boiling point. This means almost all metals are ____ at room temperature. ____ is the only exception because it is ____ at room temperature. In a pure metal all of the metal ____ are the same ____. This means the metal atoms can line up in very regular ____. Any ____ applied to the metal can make layers of atoms ____ into new ____ without breaking apart. This means the metal is ____ and easy to ____. An ____ is a mixture of more than one ____. The different metal ____ have different ____. This means that the regular pattern of metal atoms is ____. Because of this the ____ of atoms cannot ____ over each other as easily so the alloy is ____ than the pure metal.
