Molecules Flashcards
2 or more atoms held together with a chemical bond
Molecule
Connection between atoms
Chemical bond
Representation of an atom
Model
The atoms that make up a molecule + specific quantities
Atomic composition
The specific way the Atoms are arranged
Chemical structure
A molecule whose atoms occur in a constant ratio + repeating pattern
Extended structure
Structure of atoms or molecules in a 3d pattern ex. Sugar,snow, salt.
Crystal
Structure of molecules with a repeating chain pattern
Polymer
Glucose and fructose both have an atomic composition of C2H12O6 but they are different molecules. What is most likely the major difference between them?
Chemical structure
List 2 differences between crystals and polymers.
One of them is in a 3d pattern and one is shaped differently
What is an element?
One of the squares on the periodic table
What is an atom
A combination f protons neutrons and electrons
What is a molecule?
A combination of atoms
When making molecule models, what do the beads represent? The sticks?
Sticks- chemical bonds
Beads- atoms
Can you have 2 different crystals that are made of the same atom?
Yes
