What type of charge does a proton have?
Positive
100
Below is a model of C2O2, known as ethylene dione. How many atoms is one molecule of ethylene dione made of?
4 atoms
100
is this a model of a simple molecule or an extended structure?
extended structure
100
What is a pure substance?
A substance made of only one type of atom/molecule
example: gold, water
100
Below is a student's model of an oxygen molecule, O2. How can this student improve their model?
add labels or a key
200
What type of charge does a neutron have?
Neutral/No Charge/0
200
Below is a model of CH4 (methane). Is methane a molecule, compound, both, or neither (an atom/element)?
BOTH (it is a molecule since it is 2+ atoms bonded together, AND a compound because it is made of 2+ types of atoms/elements)
200
Can an extended structure be made up of many types of atoms/molecules, or is it only made of one kind?
extended structures can be made of the same or different types of atoms and molecules
200
What is matter?
Matter is anything that...
has mass and takes up space
200
below is a model of CO, carbon monoxide, that a student created. How can they improve their model?
- make them touch/bonded
- add labels or a key
- use different colors for different elements
300
What type of charge does an electron have?
Negative
300
Select a member of your team to draw a model on the whiteboard of the following molecule:
H2O3 (Trioxidane)
This model should contain
- 2 hydrogen atoms
- 3 oxygen atoms
- make sure to show bonds and label atoms
Example: 
300
Extended structures have repeating subunits or patterns that can help us identify them. Complete the pattern below.
Red, yellow, green, _____, red, yellow, green, yellow.
yellow
300
What is an atom?
what all matter is made of
the building blocks of matter
300
Is this student's model of an atom correct or incorrect? Explain your answer.
incorrect; this student has electrons inside and outside the nucleus. They should only be outside.
missing neutrons as well!
400
What subatomic particle(s) are located in the nucleus of an atom?
Protons and neutrons
400
How is a compound different than a molecule?
A molecule can be 2 or more of ANY types of atoms.
A compound has to be made of 2 or more elements (types of atoms).
400
Below is a model of glucose/mannose, C6H12O6. Is glucose a molecule or an extended structure?
Molecule-- we can tell bc there is no repeating pattern. If multiple glucose molecules bonded together, it could form an extended structure though, such as a sugar crystal.
400
What are subatomic particles?
- protons, neutrons, electrons
- sub = below/smaller
so, the smaller particles that an atom is made of
400
Is this a model of atoms, molecules, or compounds? How do you know?
atoms
They are not touching/bonded
500
What subatomic particle(s) are located outside the nucleus of an atom?
Electrons
500
Is this a model of simple molecules or an extended structure?
Model of simple molecules
It is actually the particles that air is made of! :)
500
How can I tell if I am looking at a model of an extended structure?
- multiple molecules
- bonded together
- REPEATING SUBUNITS (molecules/monomers) OR PATTERN
500
What is a model?
A picture, drawing, video, etc. that we use in science to study and learn
500
Why do we need to use models to study atoms?
atoms are too small to see with our own eyes
the SCALE!!! atoms are so small we have to zoom in to a different scale to be able to see them
