100
the basic building block of matter
Atom
100
these are the connections that form between atoms
bond
100
An observable characteristic of a substance
Property
100
a characteristic or quality of an element
Property
100
anything that has mass and takes up space
Matter
100
What is the difference between an atom, molecule and element.
Atom is singular, molecule is two or more different atoms bonded together. Element is two or more of the same atoms bonded together
100
structure made up of smaller repeating units
extended structure
100
Two or more atoms joined together by chemical bonds
Molecule
100
List atleast 3 different type of physical properties
shape, size, color......
100
How much space and object takes up
Volume
100
List all three states of matter. Circle the one that has definite shape and definite volume.
Solid, Liquid and Gas
100
Explain the difference between the "ball and stick" model and the "space filling" model
Ball and stick shows the bonds and their angles while the space filling does not.
100
a substance that is composed of only one type of atom.
Element
100
Using the table which samples are pure substances?
1 and 3
100
This type of model shows how much space each atom in a molecule takes up
Space filling model
200
Ice floats on liquid water. Explain why based on the molecular structure.
The molecules in ice are more spread apart than in liquid water.
200
Explain the difference between a molecule and an extended structure
A molecule is just one unit where an extended structure is repeating molecules
200
A structure made up of smaller repeating units.
Extended structure
200
Explain what causes something to sink in water
An object sinks when its more dense than other
200
Which of the samples are mixtures?
1. Salt
2. Sugar
3. Lemonade
4. Water
3. Lemonade
200
Graphite atoms are arranged in sheets while diamonds form a compact crystal. Explain why we use graphite for something like writing with a pencil and not diamond.
Graphite atoms will break apart more easily than diamond will.
200
Explain how the properties of a substance relate to its structure
the structure of the molecules help determine the properties (shape, hardness, solubility)
200
Solids whose atoms are arranged in a highly ordered, repeating pattern.
Crystal
200
Explain why a snow flake has 6 sides
the molecules form a hexagonal crystalline structure
200
Draw a ball and stick model for CO2
1 carbon bonded to two oxygen atoms
