Question

part 4 - particle model diagrams (10 minutes)
instructions: working at a level 1 with your table partner, it will be your task to follow the next set of directions in order to create a particle model diagram.

1. when instructed to, send one of your table partners to the front of the classroom in order to acquire a white board, a dry - erase marker, and modeling clay.
2. once you have returned to your desk, use the dry - erase marker to write you and your table partner’s names at the top of the white board.
3. draw 3 boxes, approximately 6 inches by 6 inches, in the center of your white board from left to right, and space them apart evenly.
4. write the title “element” on top of the box on the far left. write “compound” on top of the box in the middle, and “mixture” over top of the box on the far right.
5. using the modeling clay, create three hard sphere models to represent the three classifications of matter.

a. element model: must contain at least 6 atoms.
b. compound model: must contain at least 6 compounds.
c. mixture model: must contain at least 6 atoms/compounds.

1. important rule: you may not mix clay of different color together. they can touch each other, however.
2. in the three boxes below, illustrate your particle model diagrams, and then respond to the following prompt questions.

review your model of element. explain, in terms of atoms, why your model represents an element. this model is an element because

review your model of compound. explain, in terms of atoms, why your model represents a compound. this model is a compound because

review your model of mixture. explain, in terms of atoms, why your model represents a mixture. this model represents a mixture because

Explanation:

An element is made up of only one - type of atom. In the element model, all atoms are identical. A compound consists of two or more different types of atoms chemically bonded together. In the compound model, there are multiple atoms of different types bonded. A mixture contains two or more different substances (atoms or compounds) that are not chemically combined. In the mixture model, different atoms or compounds are just physically together.

Answer:

• Review your model of Element. Explain, in terms of atoms, why your model represents an element. This model is an element because it contains only one - type of atom.
• Review your model of Compound. Explain, in terms of atoms, why your model represents a compound. This model is a compound because it contains two or more different types of atoms chemically bonded together.
• Review your model of Mixture. Explain, in terms of atoms, why your model represents a mixture. This model represents a mixture because it contains two or more different atoms or compounds that are not chemically combined.
