Molecules Flashcards
2 or more atoms held together with a chemical bond
Molecule
Connection between atoms
Chemical bond
Representation of an object
Model
Atoms that make up a molecule and the specific quantities
Atomic composition
The specific way the atoms are arranged
Chemical structure
Molecules whose atom occurs in a constant ratio to repeating patterns
Extended structure
Structure of molecules in a 3D pattern
Crystal
Structure of molecules with repeating chain pattern many
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 chemical structure
List 2 differences between crystals and polymers
Crystal-molecules are in a 3D pattern
Can be a single type atom or molecules
Polymer-molecules are in a repeating chain pattern
Made of only molecules in chains
What is an element
A substance whose atoms have the same number of protons
What’s an atom
The basic unit of an element
What is a molecule
2 or more atoms held together with a chemical bond
When making molecule models what do the beads and sticks represent
Beads-atoms
Sticks-chemical bonds
Can you have 2 different crystals that are made of the same atom
Yes crystals can change with a change in temperature and pressure
