The radial distribution functions [P(r)] is used to determine the most probable radius, which is used to find the electron in a given orbital 
for 1s-orbital of hydrogen like atom having atomic number Z, is 
= 
:
A
At the point of maximum value of radial distribution function 
= 0; one antinode is present
= 0; one antinode is present
B
Most probable radius of Li 2+ is 
pm
pm
C
Most probable radius of He + is 
pm
pm
D
Most probable radius of hydrogen atom is a 0 pm
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a,b,c,d) At the point of maximum value of RDF
= 0
= 0; r = 
where Z = 3 for Li 2+ and Z = 2 for the He + ;
Z = 1 for hydrogen.
