Question

how to find atomic radii and ionic radii of a element??​

Answer 1

Answer:

Divide the distance between the nuclei of the atoms by two if the bond is covalent. For example, if you know the distance between the nuclei of two covalently bonded atoms is 100 picometers (pm), the radius of each individual atom is 50 pm.

The ionic radius is half the distance between atomic ions in a crystal lattice. To find the value, ions are treated as if they were hard spheres. The size of an element's ionic radius follows a predictable trend on the periodic table. As you move down a column or group, ionic radius increases.

Answer 2

Answer:

atomic is the distance away from the nucleus. atomic radius increases going from top to bottom and decrease across going to the periodic table .ionic radius is the distance away from the central atom. ionic radius increases from top to bottom and decrease across the periodic table .
