Answer 1

Answer:

b

Explanation:

less than crystal radius

Answer 2

Crystal radius is generally (c) greater than the univalent radius.

What is the metallic or crystal radius?

• One-half of the distance between the nuclei of two adjacent atoms in a crystal or between two adjacent metal ions in a metallic lattice is referred to as the metallic radius.
• The ionic radius serves as a gauge for the size of an atom's ion in a crystal lattice.
• Ionic atoms grow in size relative to their parent atom when they are produced.
• In comparison to their neutral atoms, cation radii will grow smaller and anion radii larger.

About Atomic radius:

• A chemical element's atomic radius, which is typically the average or typical distance between the nucleus's core and the outermost isolated electron, serves as a gauge for the size of an atom.
• There are numerous non-equivalent definitions of atomic radius since the border is not a clearly defined physical entity.
