The electron density of aluminum is high, which means it has a strong metallic bonding. This gives aluminum properties such as high electrical and thermal conductivity, malleability, and ductility.

Electron density refers to the distribution of electrons around an atom or molecule. It affects the properties of atoms and molecules by influencing their reactivity, stability, and physical characteristics. Higher electron density can lead to stronger chemical bonds and increased stability, while lower electron density can result in higher reactivity and weaker bonds. Overall, electron density plays a crucial role in determining the behavior and properties of atoms and molecules.
The density of the metal in the crushed can is the same as the metal's density before the can was crushed. Density is a physical property that remains constant regardless of the shape or size of the object.
Resonance is important because it allows molecules to be more stable by distributing electron density more evenly. This can help stabilize reactive intermediates in organic reactions. Additionally, resonance can affect the reactivity and properties of a molecule, influencing its chemical behavior.
The properties of a material, such as its density and refractive index, affect how light is refracted and reflected. When light passes through a material with a different density or refractive index, it can change direction (refraction) or bounce off the surface (reflection). The angle at which light enters the material also plays a role in how it is refracted or reflected.
The properties of air that affect lift include its density (less dense air generates more lift), temperature (warmer air is less dense and can affect lift), pressure (lower pressure can decrease lift), and humidity (moist air is less dense and can reduce lift).
