Question

What is the value of Principle and Azimuthal quantum numbers in 3P electrons ?

1 point

3 and 0 respectively

3 and 2 resp.

4 and 3 resp.

3 and 1 resp.​

Answer 1

Answer:

If n and l are principal and azimuthal quantum numbers respectively, then the expression for calculating the total number of electrons in any energy level is  

1=N-1

∑   ​  2(2l+1)

1=0

Thus, s-subshell (l=0) contain 2 electrons.

p-subshell (l=1) contain 6 electrons.

d-subshell (l=2) contain 10 electrons.

f-subshell (l=3) contain 14 electrons.

Answer 2

The value of Principle and Azimuthal Quantum numbers 3p electron is 3 and 1 respectively. (OPTION D)

QUANTUM NUMBERS -

• The set of numbers to describe electrons in a shell of an atom.
• Four types of quantum numbers are - Principle, Azimuthal, Magnetic, and spin quantum number.

1. Principle Quantum number - explains the position of the electron in a shell.

• It gives information on the energy level of the electron.
• Denoted by the symbol 'n' and value ranges from 1 to infinity.

2. Azimuthal QUantum number - denotes the subshell of the residing electrons.

• It infers the magnitude of orbital angular momentum.
• Denoted by the symbol 'l' and value ranges between 0 to (n-1).
• The subshells s,p,d, and f are denoted as 0,1,2, and 3 respectively.

As per the quantum number rule, in 3p -

3 is the principle quantum number, and

p is the subshell denoted with number 1.
