Atomic Structure WebQuest

Introduction Atoms are the basis of chemistry. They are the basis for everything in the Universe. You should start by remembering that matter is composed of atoms. If you want to do a little more thinking, start with particles of matter. Matter, the stuff around us, is used to create atoms. Atoms are used to create the elements. Elements are used to create molecules. It just goes on. Everything you see is built by using something else.

The Task You are to use the suggested websites to gather information and answer the questions or statements on the sheet.

Basic Atomic Structure: go to http://www.chem4kids.com/files/atom_structure.html

  1. Describe how atoms are like building blocks


  1. What are the three basic parts of an atom? Draw a basic picture of an atom.


  1. What particles are located in the nucleus? What is the charge for each particle?


  1. Where are electrons located? What is the charge for this particle?


  1. If the charge on the atom is 0, what does this mean?


Subatomic Particles: go to for the following websites:

11. The electron cloud has a radius ___________ times ____________ than the nucleus.

12. The number of protons in an atom defines what _____________ it is. For example, ____________atoms have six protons, ____________ atoms have one and ___________ atoms have eight. The number of protons in an atom is referred to as the ____________ _______________ of that element.

13. What happens when the number of protons in an atom changes?


14. Does the same thing happen if the number of electrons change?


Go to the bottom of the page and practice BUILD AN ATOM.


15. Go to: http://studyjams.scholastic.com/studyjams/jams/science/matter/atoms.htm

then click the “test yourself” button.


Record your score here:___________


WHEN YOU FINISH, GO TO: http://www.ptable.com AND WRITE AS MANY WORDS AS YOU CAN MAKE UP USING THE ELEMENTS. Example: CAt (Carbon and Astatine)
