CORRECT SOLUTIONS
Atomic Radius - ✔✔Distance from nucleus to outermost electron.



Nonbonding Atomic Radius - ✔✔Radius when atoms are not bonded; van der Waals radius.



Bonding Atomic Radius - ✔✔Radius when atoms are bonded; covalent radius.



Covalent Radius - ✔✔Half the distance between bonded nonmetal atoms.



Metallic Radius - ✔✔Half the distance between adjacent metal atoms.



Van der Waals Radius - ✔✔Radius of an atom not bonded to another.



Atomic Radius Measurement - ✔✔Average bonding radii from multiple elements.



Periodic Trend - ✔✔Systematic variation of atomic radius in the periodic table.



Atomic Radius Increase - ✔✔Occurs down a column in the periodic table.



Atomic Radius Decrease - ✔✔Occurs across a period from left to right.



Bond Length - ✔✔Sum of atomic radii of bonded atoms.

, Example of Bond Length - ✔✔ICl bond length is 232 pm.



Krypton Atomic Radius - ✔✔Determined by distance in solid krypton.
