Properties of Metals
This page focuses on the specific properties of metals that arise from their unique bonding structure, particularly their conductivity and malleability.
Why metals are good conductors of heat and electricity:
The excellent conductivity of metals is a direct result of their bonding structure.
Definition: Electrical conductivity in metals is the ability of the material to allow the flow of electric current through it.
- Electrical Conductivity: Metals are excellent conductors of electricity because the delocalized electrons are free to move throughout the metal structure. When an electric potential is applied, these electrons can easily flow, creating an electric current.
Example: In a copper wire, the delocalized electrons move freely through the metal, allowing it to conduct electricity efficiently in electrical circuits.
- Thermal Conductivity: Metals are also good conductors of heat. When a metal is heated, the delocalized electrons can move and carry thermal energy throughout the material.
Highlight: The same delocalized electrons responsible for electrical conductivity also contribute to the thermal conductivity of metals.
Malleability and Ductility of Metals:
Metals are known for their malleability (ability to be hammered into thin sheets) and ductility (ability to be drawn into wires). These properties are also a result of their bonding structure.
Vocabulary: Malleability is the ability of a metal to be deformed under compressive stress, while ductility is the ability to be stretched into a wire without breaking.
When force is applied to a metal, the layers of positive ions can slide over one another without breaking the metallic bond. The sea of delocalized electrons continues to hold the structure together, allowing the metal to change shape without fracturing.
Example: Gold can be hammered into extremely thin sheets (gold leaf) due to its high malleability, a property that stems from its metallic bonding structure.
These properties make metals incredibly versatile materials, used in a wide range of applications from electrical wiring to construction and manufacturing.
Metallic Bonding
Metallic bonding is a fundamental concept in chemistry that explains the unique properties of metals. This page delves into the structure and nature of metallic bonds.
Definition: Metallic bonding is an electrostatic attraction between positive metal ions and negatively delocalized electrons from the outer shell.
The structure of metals consists of a giant lattice where ions are packed closely together in layers. This arrangement forms a regular pattern of atoms throughout the metal.
Vocabulary: Delocalized electrons are electrons that are not associated with any specific atom or bond but are free to move throughout the metal structure.
In metallic bonding, the outer shell electrons of metal atoms become delocalized, creating a 'sea' of electrons that surrounds the positively charged metal ions. This unique arrangement contributes to the distinctive properties of metals.
Example: A metallic bonding diagram typically shows positively charged metal ions surrounded by a cloud of negatively charged, freely moving electrons.
Properties of metals resulting from metallic bonding include:
- High melting and boiling points
- Malleability and ductility
- Excellent conductivity of heat and electricity
Highlight: The high melting and boiling points of metals are due to the strong electrostatic forces of attraction between the positive ions and the sea of delocalized electrons.
The good conductivity of metals is attributed to the mobility of the delocalized electrons, which can easily carry electric current or thermal energy throughout the metal structure.
Quote: "Metals consist of giant structures of atoms arranged in a regular pattern. The electrons in the outer shell of metal atoms are lost, and are free to move throughout the structure."

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
