Molecules Flashcards
Molecule
Two or more atoms held together with a chemical bond
Chemical bond
Connection between atoms
Model
A representation of an object
Atomic composition
The atoms that make up a molecule and the specific quantity
Extended structure
A molecule who’s atoms occur in a constant ratio and repeating pattern
Chemical structure
The specific way atoms are arranged
Crystal
Structure of atoms or molecules in a 3 D pattern
Polymers
A structure of molecules with a repeating chain pattern
Glucose and fructose both have an atomic composition of C2H12O6 but they are different molecules. What is most likely the major difference between them?
The chemical structure
List 2 differences between crystals and polymers
Crystals are arranged in a 3D pattern while polymers are arranged in a chain pattern and crystals have atoms and molecules while polymers are just molecules
What’s an element?
A square on the periodic table
What is an atom?
The smallest unit of an element
What is a molecule?
Two or more atoms held together with a chemical bond
When making models, what do the beads represent? The sticks?
The beads are atoms and the sticks are chemical bonds
Can you have two different crystals that are made of the same atom?
Yes but the structure will be different
