Molecule Vocab Flashcards
Molecule
Two 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 3-D pattern
Polymer
Structure of molecules in a repeating chain pattern
Extended structure
A molecule whose atoms occurred in a constant ratio and repeating pattern
Ratio
A quantity relationship between two things
Glucose and fructose both have an atomic composition of C6H,20 but they are different molecules. What is most likely the major difference between them?
The structure changes the properties
List 2 differences between crystals and polymers.
Crystals are 3-D and have molecules and atoms
Polymers are patterns and only have molecules
What is an element?
Anything on the periodic table
When making molecule models, what do the beads represent? The sticks?
Beads = atoms sticks=chemical 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 red phosphorus and white phosphorus. They have the same atoms. They have different colors shapes and structures.
C3H4 has how many elements? Atoms?
2 elements. 7atoms
