Practice Problem: Atomic Radii and Ionic Radii

The video tutorial covers the concepts of atomic and ionic radii, explaining how atomic radius increases as you move left and down the periodic table due to fewer protons and additional electron shells. It also discusses ionic radii, focusing on isoelectronic species and how the number of protons affects ionic size. The tutorial provides examples and trends to help understand these concepts.

Identify the ions discussed in the text and their corresponding electron counts.

How does the number of protons in the nucleus affect the ionic radius of isoelectronic species?

What is the correct order of the following ions in terms of increasing ionic radius: O2-, Mg2+, F-, Na+, Ne?
