Modeling Matter

Crystal

Solids whose atoms are arranged in a highly ordered and repeating pattern

Polymer

One large molecule made of smaller repeating molecules

extended structure

structure made of smaller repeating units

pure substances

a substance made of 1 type of molecule or atom

compound

The result of different atoms and molecules joining together

chemical bond

The connections between atoms

How is oxygen different from helium

oxygen is a simple molecule, made of 2 oxygen atoms in a linear structure

How is helium different from oxygen

Helium is an element, whereas oxygen is a simple molecule

Why do snowflakes have common shapes

Their structure of their atoms is similar, being a hexagonal shape

How is an element different from a compound

an element is different because elements are made from 1 atoms, whereas compounds are atoms of different elements

What are helium and oxygen’s chemical symols

He (Helium), O (Oxygen)

What is water and salt’s chemical formula

H_²O, NaCl

What is the chemical formula for fructose

C₆H₁₂O₆

What elements make up Fructose

Carbon, hydrogen, and oxygen

What is the relationship between molecules, compounds, and pure substances

atoms that are joined together are molecules and molecules and atoms form together to make compounds, which are all pure substances

What are the benefits of a space filling model

It helps represent the shape and size of the atoms

What are the benefits of the ball and stick

It helps see the bonds and placement more clearly

What are the benefits of the structural diagram model

The simplicity helps track how substances change in a reaction

What is salt’s molecular structure? How does it affect its function

Salt’s molecular structure it’s function because it has a rigid structure, making it’s properties rigid on a larger scale

How does Nylon’s structure affect it’s function?

Nylon is a polymer and its structure is flexible and strong, which helps parachutes fold and catch air

How do models help us understand matter at different scales

Since matter is too small to see, people model matter so they can see it’s molecular structure that gives it properties on a larger scale
