Molecules Flashcards
Molecule
2 or more atoms held together with a chemical bond
Chemical bond
Connection between atoms
Model
Representation of an object
Atomic composition
The atoms that make up a molecule and the specific quantity
Extended structure
A molecule whose atoms occur in a constant ratio and repeating pattern
Crystals
Structure of atoms or molecules in a 3D pattern
Polymer
Structure of molecules with a repeating chin pattern
Crystal structure
Structure of atoms or molecules in a 3D pattern Ex. Snowflakes, sugar, salt
- Glucose and fructose both have an atomic composition of C6H12O6 but they are different molecules. What is most likely the major difference between them?
Different structures
List 2 differences between crystals and polymers. Hint: one is shape and one is composition.
The ratio and atoms
What is an element?
A substance that can’t be broken down into smaller parts.
What is an atom?
The smallest unit of measurement
What is a molecule?
2 or more atoms held together
When making molecule models, what do the beads represent? The sticks?
The beads represent atoms and the sticks represent the chemical bonds
Can you have 2 different crystals that are made of the same atom?
Yes because they have the same chemical bond
