Molecules Flashcards
(17 cards)
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 occur in a constant ratio and repeating pattern
Ratio
A quantity relationship between two 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?
The major difference between glucose and fructose are probably the way the chemical structures are arranged.
List 2 differences between crystals and polymers
Crystals show the structure of atoms or molecules in a 3-D pattern but polymers show the structure in repeating chain pattern. Crystals can be one or more types of elements, but polymers have to be more than one element.
C3H4 has how many elements? Atoms?
C3H4 has 2 elements and seven atoms.
What is an element?
One type of atom and is represented by one square on the periodic table.
What is an atom?
An atom is the smallest unit of matter that has the properties of an element.
What is a molecule?
A molecule is when two or more atoms are bonded together.
When making molecule models, what do the beads represent? The sticks?
The beads represent the atoms that the sticks represent the bonds.
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 the same because they both contain carbon atoms, but they are different because of how their chemical structures are arranged.
