Explanation:
To find the total number of electrons having n l=5 in Mo(42) atom in its ground state, we need to find the electronic configuration of the Mo(42) atom.
The electronic configuration of Mo(42) atom is as follows:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d⁴
Breakdown of electronic configuration:
- The first shell has 2 electrons (1s²)
- The second shell has 8 electrons (2s² 2p⁶)
- The third shell has 8 electrons (3s² 3p⁶)
- The fourth shell has 18 electrons (4s² 3d¹⁰ 4p⁶)
- The fifth shell has 2 electrons (5s²) and 4 electrons (4d⁴)
The n l=5 means that the electron is in the fifth shell and has an angular momentum quantum number of 5. The angular momentum quantum number l can have values ranging from 0 to n-1. Hence, for n=5, l can have values of 0, 1, 2, 3, and 4.
Breakdown of n l=5:
- l=0 corresponds to the s orbital
- l=1 corresponds to the p orbital
- l=2 corresponds to the d orbital
- l=3 corresponds to the f orbital
- l=4 corresponds to the g orbital
Therefore, for the n l=5, we need to consider the d orbitals as they have l=2.
Answer:
The total number of electrons having n l=5 in Mo(42) atom in its ground state is 4 as there are 4 electrons in the 4d orbitals. Hence, the correct option is 4)17.
