Valence Electrons in Bohrium (Bh)
Calculate the number of valence electrons in Bohrium using its electron configuration step by step.
Valence Electrons in Bohrium
Determine the number of valence electrons in Bohrium (Bh, Element 107)
Step 1: Look up the electronic configuration for Bohrium
The abbreviated (condensed) ground electronic configuration for Bohrium is:
[Rn] 5f14 6d5 7s2
Calculate Electronic Configuration for Bohrium
Step 2: Identify the outermost electrons using the electronic configuration
Electrons in atomic orbitals outside the [Rn] core are the outermost electrons:
5f14 6d5 7s2
Step 3: Use the principle quantum number to identify the valence electrons
Extract the principle quantum number, n, and number of electrons from the electron configuration:
| Electron Configuration | n | Orbital | Number of Electrons |
|---|---|---|---|
| 5f14 | 5 | f | 14 |
| 6d5 | 6 | d | 5 |
| 7s2 | 7 | s | 2 |
The outermost electrons with the largest principal quantum number (in this case, n = 7) are valence electrons.
Answer
Bohrium (Bh) has 2 valence electron(s).
