Molecules Flashcards
2 or more atoms held together with a chemical bond
Molecules
Connection between atoms
Chemical bond
Representation of an object
Model
Atoms that make up a molecule and the specific quantity
Atomic composition
A molecule whose atoms occur in a constant ratio and repeating pattern
Extended structure
The specific way atoms are organized
Chemical structure
Structure of atoms or molecules in a 3D pattern
Crystal
Structure of molecules with a repeating chain pattern
Polymer
Glucose and fructose both have an atomic composition of C6H12O6 but they are different molecules. What is most likely the major difference between them?
The major difference is probably the structure of the two molecules are different.
List 2 differences between crystals and polymers. Hint: one is shape and one is composition.
1Crystals can be atoms and molecules and polymers can only be molecules
2Crystals are 3D and polymers are chains
What is an element?
One square on the periodic table
What is an atom?
The smallest unit of an element
What is a molecule?
2 or more atoms bonded
When making molecule models, what do the beads represent? The sticks?
The beads represent atoms, the stick represent the chemical bond
Can you have 2 different crystals that are made of the same atom?
Yes, because they have different structures
