3p orbital has -

1. Two spherical nodes

2. Two non-spherical nodes

3. One spherical and one non-spherical node

4. One spherical and two non-spherical nodes

The correct order of the total number of nodes of atomic orbitals is: 

1.  4f > 6s > 5d

2.  6s > 5d > 4f

3.  4f > 5d > 6s

4.  5d > 4f > 6s

Correct statement among the following is: 

1.  Number of angular nodes = n - l - 1

2.  Number of radial nodes = l

3.  Total number of nodes = n -1

4.  All of the above

Maximum number of total nodes is present in:

1.  5s

2.  5p

3.  5d

4.  All have same number of nodes

Orbitals having two spherical nodes are: 

Each questions contains STATEMENT-1 (Assertion) and STATEMENT2- (Reason).

Examine the statements carefully and mark the correct answer according to the instructions given below:

Statement-1: Orbital having xz plane as node may be 3d_xy.

Statement-2: 3d_xy has zero radial node.

1.  If both the statement are true and statement -2 is the correct explanation of statement-1

2.  If both the statements are true but statement-2 is not the correct explanation of statement-1

3.  If statement-1 is true and statement-2 is false

4.  If statement-1 is false and statement-2 is true

In a subshell, if the number of radial nodes is two times the number of angular nodes, then the minimum possible value of the principal quantum number (n) is: 

[angular nodes are non-zero)

Orbital having 3 angular nodes and 3 total nodes is:
1. 5 p
2. 3 d
3. 4 f
4. 6 d

Assertion: The number of radials and angular nodes for 3p orbital is 1, 1 respectively.

Reason: The number of radials and angular nodes depends only on the principal quantum number.

1. both assertion and reason are true and the reason is the correct explanation of assertion.

2. both assertion and reason are true but the reason is not the correct explanation of
assertion.

3. assertion is true but the reason is false

4. both assertion and reason are false

The number of radial nodes of 3s and 2p-orbitals are respectively:

(1) 2,0

(2) 0,2

(3) 1,2 

(4) 2,1
