Molecule Flashcards
(17 cards)
Molecule
2 or more atoms bonded together
Chemical Bond
Connection between atoms
Chemical Formula
the atoms (letters and numbers) that make up a molecule
Model
Representation of an object
Chemical Structure
The specific way that atoms are arranged
Crystal
Structure of an atom 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?
They have different structures
List 2 differences between crystals and polymers.
Crystals are 3D models, and polymers are a repeating chain. A crystal can be 1 or more elements, while a polymer requires 2 or more elements.
What is an element?
1 type of atom, and it’s represented by a square on the periodic table
What is an atom?
The smallest unit of matter
What is a molecule?
A joining of two or more atoms
What is a molecule?
A joining of two or more atoms
When making molecule models, what do the beads represent? The sticks
The beads represent the atoms, and the sticks represent the 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, Diamonds and Graphite are both pure carbon. However, they have different structures with let’s diamonds be much harder than graphite
