Molecule Vocab 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
Structures of atoms or molecules 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
Quality relationship between two things.
Glucose and fructose both have an atomic composition of C6H,206 but they are different molecules. What is most likely the major difference between them?
The difference between them would be that oxygen and hydrogen are in the same group, but carbons in a different group so that means that carbon is different from hydrogen and oxygen in and chemical structure.
List 2 differences between crystals and polymers
polymers are molecules in a repeating
chain and crystals are a 3D
Polymer is molecule
crystal is atoms and molecules
C3H4 has how many elements? Atoms?
Their are 2 elements and their are 7 atoms in all.
What is an element?
Each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number.
What is an atom?
Smallest unit of matter that has the same properties of an element.
What is a molecule?
Two or more atoms bonded together.
When making molecule models, what do the beads represent? The sticks?
The circles represent the chemical elements and the sticks represent the connectors that connect the chemical elements.
you have 2 different crystals that are made of the same atom? Give an example.
Diamond and graphite for example they are both pure carbon and they are both pure substances made of carbon atoms. However diamonds are one of the hardest substances on Earth and graphite is easy to break apart and soft.
