What is metallic bonding?
Metallic bonding is the attraction between positive metal ions and delocalised electrons.
What are delocalised electrons in metals?
Delocalised electrons are electrons in metals that do not belong to any particular metal atom and are free to move throughout the metal lattice.
Why can metals conduct electricity?
Metals can conduct electricity because they have free electrons available to move and carry charge.
What allows metals to be malleable and ductile?
Metals are malleable and ductile because the layers of positive ions can slide over one another.
True or False?
Alloys are created by mixing a metal with another metal or non-metal.
True.
Alloys are created by mixing a metal with another metal or non-metal.
Why do metals have high melting and boiling points?
Metals have high melting and boiling points because they contain many strong metallic bonds, which require a lot of heat energy to overcome.
Describe the structure of a metal.
Metal structures are positive metal ions arranged in a regular pattern, with a "sea" of delocalised electrons moving freely between them.
True or False?
Metallic bonds are strong due to the attraction between negative metal ions and delocalised electrons.
False.
Metallic bonds are strong due to the attraction between positive metal ions and delocalised electrons.
