Molecule Vocab Flashcards
Molecule
2 or more atoms bonded together.
Chemical bond
Connections 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 repeated 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?
The chemical structure.
- List 2 differences between crystals and polymers.
- crystals= 3D pattern, polymer: repeated chain pattern.
- C3H4 has how many elements? Atoms?
2 elements, 7 atoms
- What is an element?
A pure substance made of only type of atom
- What is an atom?
The basic building block in chemistry, and it is the smallest part of a substance that cannot be broken down chemically.
15 What is a molecule?
Two more more atoms bonded together.
16 When making molecule models, what do the beads represent? The sticks?
17 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?
