(17 cards)
Molecule
2 or more atoms bonded together
Chemical bond
Connection between atoms
Model
Representation of an object
Chemical formula
The atoms (letters and numbers) that make up a molecule
Chemical structure
The specific way that atoms are arranged
Crystal
Structure of atoms or molecules in a 3D pattern
Polymer
Structure of molecules in a repeating chain pattern
Extended structure
A molecule whose atoms occur in a constant ratio+repeating pattern
Ratio
A quantity relationship between 2 things
Glucose and fructose both have an atomic composition of C6H12O6 but they are different molecules. What is most likely the major difference between them?
They have different structures.
List 2 differences between crystals and polymers
They both have different patterns.
Crystal is structure of atoms while polymer is the structure of molecules.
C3H4 has how many elements? Atoms?
2 elements and 7 atoms
What is an element
Every square on the periodic table
What is an atom?
An atom is the smallest unit of matter
What is a molecule?
2 or more atoms bonded together.
When making molecule models, what do the beads represent? The sticks?
The beads represent atoms and the sticks represent the bonds
Can you have 2 different crystals that are made of the same atom? Give an example. How is it the same? How is it different?
Yes, because diamonds and graphite are both made up of carbon, but they’re so different, because of the different structure.
