Question

b)Write the values of all four quantum numbers for 2p electrons.
Discuss their significance in brief.

Answer 1

The values of all 4 quantum numbers for 2P electrons are as follows:

1. n = 2

2. l = 1

3. ml = -1.0, + 1

4. ms = -1/2 or +1/2

n is a fundamental quantum number that determines the energy of the electron, as well as the

size of the orbital.

l denotes the form of an orbital associated with a particular basic quantum number. this value

goes from 0 to n-1.

ml is a magnetic quantum number dividing suboblocki into separate orbitals that hold electrons; in

each podbolochki there are 2 + 1 orbitals.

The last ms is the quantum number of the spin, which defines the orientation of the axis of

rotation of the electron.
