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 13 and add at least 1 additional Reason to explain why the claim you chose is true.
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.
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.
