Molecules Flashcards
(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 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 occurring constant ratio and reapeating 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?
Chemical structure
C3H4 has how many elements? Atoms?
7 atoms 2 elements
What is an element?
An element is entirely made up of the same atom.
What is an atom
It makes up everything and is the smallest part of matter.
What is molecules?
A substance that is made up of more than one atom.
When making molecules models, what do the beads represent? The sticks?
Beads are atoms sticks are bonds
List 2 differences between crystals and polymers.
Crystals are 3d and polymers are a repeating chain. Polymer has one or more elements. Crystals can have one type of element.
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 diamonds and graphite they have different chemical structures but the same element.
