Structure & Bonding (w/Giant Ionic Lattice)

Giant Ionic Lattice

A three-dimensional structure formed by ionic compounds where each ion is attracted to multiple oppositely charged ions.

Conductivity in Ionic Compounds

Ionic compounds do not conduct electricity in solid form due to fixed ion positions, but they do conduct when in liquid or aqueous form.

Brittleness of Ionic Compounds

Ionic compounds are brittle because like charges repel each other, causing the structure to break apart when under stress.

Allotropes

Different structural forms of the same element, such as diamond and graphite, that exhibit distinct properties.

Delocalised Electrons

Electrons that are not bound to a specific atom and can move freely, contributing to electrical conductivity.

Melting Point of Diamond

Diamond has a melting point of 4830°C, making it incredibly heat resistant.

Graphite

An allotrope of carbon consisting of layers of carbon atoms, known for being a good conductor of electricity and heat.

Metallic Bonding

Bonding characteristic of metal where delocalised electrons allow cations to remain in a lattice structure.

Malleability of Metals

The ability of metals to deform under stress due to the delocalised nature of the bonding electrons.

Alloys

Mixed metals with at least one additional metal added, which changes the properties compared to pure metals.
