Question

Which of the following orbitals is the largest in size?
A. 2s
B. 4s
C. 1s
D. 3s
E. all s orbitals are the same size

Answer 1

The answer would be B.

Answer 2

The orbital which is the largest in size is 4s.

Hence option (B) is correct.

What is Shape of S-orbital ?

The shape of s-orbital is spherical around the nucleus of the atom. S-orbital have the probability to find the electrons at a given distance which is equal in all the directions.

Now lets check all options one by one

Option (A): 2s is a larger sphere than 1s but not 4s.

So, option A is incorrect.

Option (B): Here 1s is a small sphere, 2s is a larger sphere, 3s is more larger than 2s and 1s and 4s is the largest orbital from all of these.

So, option B is correct.  

Option (C): 1s is smallest sphere from all of these.

So option C is incorrect.

Option (D): 3s is also smaller than 4s orbital.

So option D is incorrect.

Option (E): All the s-orbital have the same shape which is spherical not same size.

So option E is incorrect.  

Thus, from above conclusion we can say that the orbitals which is largest in size is 4s.

The correct answer is option (B).
