Diamond
Structure explains properties
Reason it through
How does diamond’s bonding connect to its properties?
First link · your turn
Start with one carbon atom: how many covalent bonds does it form?
Build the explanation
Follow the reasoning from one carbon atom to the properties of the whole substance.
- One carbon atomEach carbon atom forms four covalent bonds with other carbon atoms.
- Bonds continueThose bonded carbon atoms form a giant covalent structure.
- Structure sets propertiesThe structure and bonding make diamond very hard and give it a very high melting point.
- Electrical propertyDiamond also does not conduct electricity, another property linked to its structure and bonding.
Relationship matrix
Tap any cell to reveal it. Tap a column header to read one property down every item.
Each cell hides a short answer and the reason behind it. Predict before you tap.
Predict from the structure
Use the bonding information before revealing the property set.
A substance is diamond: each carbon atom forms four covalent bonds in a giant covalent structure. Which property set matches it?
Explain, don't just list
Problem
Explain the properties of diamond in terms of its structure and bonding.
WHAT YOU'VE LEARNED
A quick recap of today's lesson.
Four covalent bonds per carbon atom build the structure behind diamond’s distinctive properties.
