Molecule Vocab Flashcards
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 and 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?
Their chemical structure is the major difference
C3H4 ha show many elements? Atoms?
2 elements 7 atoms
List two differences between crystals and polymers
Crystals do not have a bond, but there’s a bond for polymer
What is an element?
Something made of one atom
What is an atom?
Basic building blocks of matter and the smallest unit of measure
What is a molecule?
A bond between atoms
When making models, what do the beads represent? Sticks?
The beads show the detailed shape of the entire section. The sticks show the bond.
Can you have two different crystals that are made of the same atom? Give an example. How is it the same? How is it different?
Yes, diamond and graphite are both made of carbon, but the atoms are arranged differently.
