These Task Cards are meant to help students understand the basics of Ions and Net Charge, a perfect introductory activity.
TEK 8.5A Describe the structure of atoms, including the masses, electrical charges, and locations, of protons and neutrons in the nucleus and electrons in the electron cloud.
TEK 8.5B Identify that protons determine an element's identity and valence electrons determine its chemical properties, including reactivity.
When looking at a task card, the student will need to be able to identify the protons and electrons in each element in order to find the net charge of the atom present. They will record the number of protons and electrons on the answer sheet, to help them with finding the net charge. Hopefully they will begin to see a pattern and start to understand how atoms react with one another based on their electrical charge (Na+ connects with Cl– to make NaCl, salt) These task cards can be used in a variety of ways. You can hang them up in your classroom as is or in hallways for kids to work on answering the different portions of each card. They can be printed multiple to a page, to be handed out as a warmup as well. Each Card has a QR code so that students can check their answers with their devices or you can use the attached answer key. On the answer key the number associated with each box corresponds to the atomic number of each element. So if a student starts off with Oxygen, they must find number 8 on their answer key and fill in that box.
There is a set with QR codes and a set without. A blank answer sheet for students to record their answers, as well as an answer key are included to help with grading.
Previews are available so that you can see what the task cards looks like to make sure it is a product you would like to use and enjoy.
