At the top left, click BUILD ME and Make at least 3 different models of atoms. Click CHECK ANSWER when you think your right!
11) Which atom you built has the largest atomic mass? What was it and how do you know?
GO TO Site 4: Read the information on this site
http://www.chem4kids.com/files/matter_intro.html and click “next page on matter” at the bottom of the pages until you find your answers.
12) How is matter defined?
13) What is required to move from one state or phase of matter to the next?
14) What are the points at which matter undergoes a phase change called?
15) What happens to the atoms during phase changes?
16) How are atoms arranged in a solid, liquid and gas?Click “atoms” at the top of the page.
17) What are atoms compared to and why?
18) List and describe the 3 parts of an atom? Include charge and location.
19) What is an orbital?
GO TO Site 5: “What is the difference between atoms and elements? Click on the link:
http://education.jlab.org/qa/atoms_and_elements.html
Answer the questions below.
20) Define element
21) Define atom
22) Define molecule
23) Define compound
GO TO Site 6: Matter In Depth
So now we know that Matter can be either a pure substance or a mixture…Let’s look at pure substances first. They can be either elements or compounds. Read the information on this site http://www.chem4kids.com/files/matter_intro.html and click “elements” at the top of the page.
24) Based on the info on this page, define “element”.
Click “atoms” at the top of the page, then click “compounds” on the right.
25) What is a molecule?
26) What is compound?
27) How are molecules and compounds different?
GO TO Site 7: Elements and Compounds
OK- now use the following link to fill in the chart that helps us figure out the differences between elements and compounds. http://www.diffen.com/difference/Compound_vs_Element
