Question

An electron is found in an orbital with one radial node and two angular nodes. Which orbital electron is it?a)4db)2dc)3dd)1sCorrect answer is option 'A'. Can you explain this answer?

Answer

Explanation:
The given information about the electron is that it is found in an orbital with one radial node and two angular nodes. This information can be used to determine the type of orbital the electron is in.

1. Radial Nodes:
Radial nodes are the points in the orbital where the probability of finding an electron is zero. The number of radial nodes in an orbital is equal to the principal quantum number (n) minus the angular momentum quantum number (l) minus 1. In this case, we are given that there is one radial node.

2. Angular Nodes:
Angular nodes are the planes in the orbital where the probability of finding an electron is zero. The number of angular nodes in an orbital is equal to the angular momentum quantum number (l). In this case, we are given that there are two angular nodes.

3. Determining the Type of Orbital:
Using the information about the number of radial and angular nodes, we can determine the type of orbital the electron is in. The types of orbitals are named using the following notation:
n, l

- n represents the principal quantum number
- l represents the angular momentum quantum number

The possible orbitals for the given electron are:
- 1s
- 2s, 2p
- 3s, 3p, 3d
- 4s, 4p, 4d, 4f

The orbital with one radial node and two angular nodes is 4d. Therefore, the correct answer is A) 4d.

Answer

The Total no. Of nodes in an orbital = (n - 1)

So in 4d orbital,

n=4, l=2 hence

No. of nodes= 4-1 = 3

No. of radial nodes in an orbital = (n - l - 1)

So, no. of nodes in 4d = 4-2-1=1

Since, no. Of angular nodes = l

=2

Hence the option d) i.e., 4d is correct.

Answer

Total number of nodes is given by...n-1 ....where n is principle quantum number......so......n-1=3.....which gives n=4.......so..answer will be 4d as l=2
