List at least 2 patterns that you notice from the data table and Periodic Table showing the atomic radius of elements.
Go back to question 16 and add an additional piece of evidence based on the atomic radius trend you notice for elements as you go across a period.
What is 1 Got and 1 Need you have?
Got- Something you're taking away or understand from this formative
Need- A question you have or a topic you want to go over more.
Compare the sizes of positive cations to the sizes of negative anions.
Use what you know about atomic structure, core charge and atomic radius patterns to explain a possible reason for why the sizes of cations are different than the sizes of anions.
Respond to 1 question below about the passage you read in question 1.
1. What is the main idea of this passage?
2. What do you think the model is showing?
3. Choose 1-2 direct quotes that are most important to understand the model
What is 1 question or idea from the passage you need clarified to understand Model 1 better?
Based on Model 1: Which of the following are true? Select all that apply
The strength of the electrostatic force of attraction within atoms is between the positively charged ______________ and negatively charged __________________.
If an element has a greater core charge it will have a ____________ electrostatic attraction holding the protons and electrons together within the atom.
Draw a Bohr Diagram of Be
Remember:
Atomic Number = protons
Protons= electrons
Atomic Mass - Atomic Number= neutrons

NOTE: You fill in the reasoning for the CLAIM that you think is correct. Leave the other side blank.
See the link that says rubric under the question # to help with response.
Why does sodium (Na) have a much larger atomic radius than argon (Ar) even though they are in the same period? CHOOSE THE BEST OPTON.
