Molecules Flashcards
Molecule
2 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 the specific quantity
Chemical structure
The specific way atoms are arranged
Extended structure
A molecule whose atom occur in a constant ratio and a repeating pattern
Crystal
Structure of atoms or molecules in a 3D pattern
Polymer
Structure of molecules with 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 and polymers. Hint:one is shape and one is composition
Polymers:chain pattern
Crystal:3D
Polymer only molecules
Crystal atoms +molecules
What is an element
A substance that can’t be broken down further
What is an atom
The smallest unit of an element
What is a molecule
2 or more atoms bonded together
Can you have 2 different crystals that are made of the same atom
Yes but the structure would be diffrent
C3H4 has how many element atoms
2 elements
7 atoms
