Molecule Vocab Flashcards
(17 cards)
molecule
2 or more atoms bonded together
chemical bond
connection between atoms
model
representation of on 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 molecute in a 3D pattern
polymer
structure of atoms or molecules in a 3D pattern
extended structure
a molecule whose atoms occur in a constant ratio and repeating pattern
ratio
aquantity relationship between 2 things
List 2 differences between crystals and
polymers.
A crystal is a solid material where atoms are arranged in a repeating order, polymers are long chains
C3H4 has how many elements? Atoms?
Elements=2 Atoms=7
What is an element?
A pure substance
What is an atom?
The smallest unit of measure
What is a molecule?
Two or more atoms bonded together
When making molecule models, what do the beads represent? The sticks?
Beads=atoms Sticks=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?
Take diamond and graphite for example they are both made of carbon, but because they have different chemical structures, they are different substances
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 chemical structures, the way their atoms are built and put together
