Valence Electrons in Hydrogen (H)
Calculate the number of valence electrons in Hydrogen using its electron configuration step by step.
Valence Electrons in Hydrogen
Determine the number of valence electrons in Hydrogen (H, Element 1)
Step 1: Look up the electronic configuration for Hydrogen
The abbreviated (condensed) ground electronic configuration for Hydrogen is:
1s1
Calculate Electronic Configuration for Hydrogen
Step 2: Identify the outermost electrons using the electronic configuration
Electrons in all the atomic orbitals are the outermost electrons:
1s1
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 |
|---|---|---|---|
| 1s1 | 1 | s | 1 |
The outermost electrons with the largest principal quantum number (in this case, n = 1) are valence electrons.
Answer
Hydrogen (H) has 1 valence electron(s).
