Molecules Vocab Flashcards
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 that atoms are arranged
Crystal
Structure of atoms or molecules in a 3d pattern
Polymer
structure of molecules in a repeating Chain pattern
a molecule whose atoms OCcur in a Constant ratio a repeating pattern
Ratio
A quantity relationship between 2 things
List 2 differences between crystals and polymers.
the arrangement of their molecules. And the size and complexity of their molecules, with crystals being molecules of smaller
C3H4 has how many elements? Atoms?
It has 7 atoms and 2 elements
What is an element?
An element is a pure substance made of only one type of atom
What is an atom?
An atom is The smallest part of a substance
What is a molecule?
The smallest particle of a substance that has all of the physical and chemical properties of that substance.
When making molecule models, what do the beads represent? The sticks?
The beads represent the atoms and the sticks represents 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?
Diamond and graphite are made from the same element, carbon. They are different because they have different structure.
Glucose and fructose both have an atomic composition of C6H1206 but they are different molecules. What is most likely the major difference between them?
Oxygen and hydrogen are in the same group and carbon is another in an other group. And they have
Different structure.
