The video tutorial covers the concepts of atomic and ionic radii, explaining how to order elements and ions by increasing radius. It begins with an introduction to the questions about atomic and ionic radii, followed by a detailed explanation of atomic radius trends on the periodic table, emphasizing the increase in size as you move left and down. The tutorial then shifts to ionic radii, focusing on isoelectronic species and how the number of protons affects ionic size. The video concludes with the correct order of elements and ions based on their radii.
