Molecules Flashcards
Molecule
Two 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 their specific quantities.
Chemical structure
The specific way atoms are arranged
Extended structure
A molecule whose atoms occur in a constant ratio and repeating pattern
Crystal
Structure of atoms or molecules in a 3d pattern
Polymer
Structure of molecules with a repeating chain pattern
Glucose and fructose both have an atomic composition of C6H12O6 but they are different molecules. What is most likely the major difference between them?
Their chemical structure
List 2 differences between crystals polymers.
Polymers are in a chain pattern and are always a molecule. A crystal is in a repeating pattern and can be an atom or a molecule.
What is 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 molecules models, what do the beads represent? The sticks?
Beads represent elements and sticks represent chemical bonds.
Can you have 2 crystals that are made of the same atom
Yes you can, but the structure can be different.
