100

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
