What is metallic bonding?

Back

Metallic bonding is the type of chemical bonding that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move around, allowing metals to conduct electricity and heat.

What is the sea of electrons model?

Back

The sea of electrons model describes metallic bonding where electrons are not bound to any specific atom but are free to move throughout the metal lattice, contributing to properties like conductivity.

List the properties of metallic bonding.

Back

Good conductors of electricity, ductile, malleable, and arranged in a crystal lattice structure.

What is an alloy?

Back

An alloy is a mixture composed of two or more elements, at least one of which is a metal, designed to enhance certain properties.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Give an example of a metal that exhibits metallic bonding.

Back

Zinc (Zn) is an example of a metal that exhibits metallic bonding.

Front

What is ductility in metals?

Back

Ductility is the ability of a metal to be stretched into a wire without breaking.

Front

What is malleability in metals?

Back

Malleability is the ability of a metal to be hammered or pressed into thin sheets without breaking.

Front

How does metallic bonding affect electrical conductivity?

Back

Metallic bonding allows for the free movement of electrons, making metals good conductors of electricity.

What is the significance of the crystal lattice structure in metals?

Back

The crystal lattice structure in metals contributes to their strength and stability, allowing them to maintain their shape under stress.
