Molecules Flashcards
two or more atoms held together with a chemical bond
molecule
connection between atoms
Chemical bond
representation of an object
model
The atoms that make up a molecule and the specific quantities
atomic composition
The specific way atoms are arranged
chemical structure
a molecule whose atom occur in a constant ratio and repeated pattern
extended structure
a structure of atoms or molecules in a 3D pattern
Crystal
structure of molecules with a repeating chain pattern
Polymer
Glucose and fructose both have an atomic composition of C6 H12 O6 but they are different molecules. What is most likely the major difference between them.
The chemical structure
List 2 differences between crystals and polymers.
Polymers are only molecules and crystals are atoms and molecules. Crystals = 3D pattern. Polymers = chain pattern
What is an element
A square on the periodic table that makes up everything
What’s an atom
An atom is the smallest unit of an element
What a molecule
2 or more atoms held together with a chemical bond
When making molecule models , what do the beads represent and the sticks.
A bead = one atom. Sticks represent the bonds
Can you have 2 different crystals that are made of the same atom
Yes
