ionic character definition
Answers: Percent ionic character is determined by finding the difference in electronegativity values (can be found in data tables) and then relating this to percentage ionic character data in another table. This http://www2.ucdsb.on.ca/tiss/stretton/database/electronegativity.htm gives you both.he concept of ionic radii is based on the assumption of a spherical ion shape. However, from a group-theoretical point of view the assumption is only justified for ions that reside on high-symmetry crystal lattice sites like Na and Cl in halite or Zn and S in sphalerite.
