<u>Answer:</u> The set of quantum numbers for the electrons in Be atom are (2, 1, -1, 1/2), (1, 0, 0, 1/2), (1, 0, 0, -1/2) and (2, 0, 0, -1/2)
<u>Explanation:</u>
There are 4 quantum numbers:
- Principal Quantum number (n) specifies the energy of the electron in a shell.
- Azimuthal Quantum number (l) specifies the shape of an orbital. The value of it lies in the range of 0 to (n-1)
- Magnetic Quantum number (m) specifies the orientation of the orbital in space. The value of it lies in the range of -l to +l
- Spin Quantum number (s) specifies the spin of an electron in an orbital. It can either have a value of
or
Berylium (Be) is the 4th element of periodic table having electronic configuration of
- <u>For electrons in 1s-orbital, the quantum numbers can be:</u>
For first electron:
For second electron:
- <u>For electrons in 2s-orbital, the quantum numbers can be:</u>
For first electron:
For second electron:
Hence, the set of quantum numbers for the electrons in Be atom are (2, 1, -1, 1/2), (1, 0, 0, 1/2), (1, 0, 0, -1/2) and (2, 0, 0, -1/2)
