(BONUS QUESTION) In the copper complexes investigated, the water and ammonia molecules act as Lewis bases (electron pair donors)
; they provide both of the electrons that form the covalent bonds between the Cu2+ ion and each ligand. Which ligand (H2O or NH3) is the stronger Lewis base? Explain your answer in terms of your answers for questions 3a and 3b. (hint: the poorer an oxidizing agent a species is, the harder it it to reduce that species. Hint #2: the copper complexes are reduced by gaining an electron.)

Answer:
The element potassium(K) with atomic number 19 has the largest atomic radius ( around 225 picometers ).
Explanation:
There is the general expected decrease from left to right with increasing nuclear charge without quantum level expansion or increase in shielding and so pulling the outer electrons closer. The 3d block of metals (Z = 21 to 30) tend to be similar and in fact tend to go through a small minimum at Mn/Fe.
The potassium been on the left most part of period , has largest radius due to least nuclear pulling effect.
