Atoms & Elements Test

As we are wrapping up our first unit, here is a list of the objectives that we covered so far. You are expected to be able to:

  • Determine the number of valence electrons in an element
  • Represent atoms using Lewis notation
  • Describe the position and electrical charge of the elementary particles in an atom (proton, electron, neutron)
  • Represent an atom of a given element using the simplified atomic model
  • Define the mole as the unit of measure of the amount of a substance
  • Express an amount of a substance in moles
  • Define isotopes as atoms of the same element whose nuclei have different numbers of neutrons and therefore different atomic masses
  • Explain the concept of relative atomic mass

You can use this as a checklist while you are studying. All of these objectives will be covered on the test.

You will get this Periodic Table on your test, but no formulas. (Note that the Periodic Table and last year’s exam formula sheet are stored in Sakai Resources > Useful Documents). 

Hello class!

Welcome to the CuleScience blog. We will be working here from time to time. In this course, we will be covering:

  • The basic structure of matter (Atoms & Elements)
  • How elements combine to form other substances and how those substances change when reactions take place (Molecules & Solutions, Changes in Matter)
  • How energy changes when an object moves or how energy changes affect an object’s movement (Energy)
  • How the soil, air, and water around us are impacted by what we do (Spheres)

Please add a comment to share ONE THING that you wonder about relating to any of the above topics.
