Molecules Flashcards
2 or mor atoms held together with a chemical bond.
Molecule
Connection between atoms
Chemical bond
Representation of an object
Model
Type of atoms that make up a molecule and the specific quantities
Atomic composition
The specific way the atoms are arranged in a molecule
Chemical structure
A molecule whose atoms accrue i a constant ratio and repeating pattern
Extended structure
Structure of atoms or molecules in a 3D pattern. (Quarts, snowflake, sugar, salt)
Crystal
Structure of molecules in a repeating chain pattern
Polymer. ( poly-many)
Glucose and Fructose have an atomic composition of C6H12O6 but they are different molecules. What is most likely the major difference between them?
They are arranged in a different pattern
What are 2 differences between crystals and polymers.
Crystals are 3D, polymers are chain like, crystals can be atoms and molecules while polymers are ONLY molecules
What is an element
Any square on the periodic table
What is an atom?
The smallest unit of an element
What is a molecule?
2 or more atoms held together with a chemical bond
When making molecules models, what do the beads represent? The sticks?
Beads are atoms and sticks are the bonds
