#Variable declaration
atomic_no=27       #Atomic on of Co
oxdn_state=3       #Oxidation state of Co
ele_donated=6*27   #Electron donated by ligand

#Calculation
EAN=atomic_no-oxdn_state+ele_donated       #Effective atomic no

#Result
print"Effective Atomic no of [Co(NH3)6]Cl3 is ",EAN,"which is equal to atomic no of Kr"

Effective Atomic no of [Co(NH3)6]Cl3 is  186 which is equal to atomic no of Kr
