The energy of orbitals increases in the order as shown below.
1 s < 2 s < 2 p < 3 s < 3 p < 4 s < 3 d < 4 p < 5 s < 4 d < 5 p < 6 s < 4 f < 5 d < 6 p < 7 s < 5 f < 6 d .
We know that , s orbital contain 2 electrons, p orbital contain 6 electrons , d orbital contain 10 electrons , f orbital contain 14 electrons.
Hence, we can count electrons present in the given atom containing half filled 6 d orbital.
| 1 s | 2 s | 2 p | 3 s | 3 p | 4 s | 3 d | 4 p | 5 s | 4 d | 5 p | 6 s | 4 f | 5 d | 6 p | 7 s | 5 f | 6 d |
| 2 | 2 | 6 | 2 | 6 | 2 | 10 | 6 | 2 | 10 | 6 | 2 | 14 | 10 | 6 | 2 | 14 | 5 |
Total electrons in the atom are 107.
This means that , atomic number of an atom is 107.
The element having atomic number 107 is Bohrium ( Bh )
