Worksheet: Atomic and Ionic Radii
In this worksheet, we will practice comparing the radii of atoms and ions, identifying and explaining trends across the periodic table.
ions in the unit cell of a mineral can be exchanged for cations of a different element with no change in structure. The radius of the ion is 86 pm. Which of the following is the most likely identity of the substituted cation, assuming differences in charge can be neglected?
- A (radius 90 pm)
- B (radius 68 pm)
- C (radius 59 pm)
- D (radius 114 pm)
- E (radius 116 pm)
