Here are the number of valence electrons for each of the following elements:
- Hydrogen (H) - 1 valence electron
- Helium (He) - 2 valence electrons
- Lithium (Li) - 1 valence electron
- Beryllium (Be) - 2 valence electrons
- Boron (B) - 3 valence electrons
- Carbon (C) - 4 valence electrons
- Nitrogen (N) - 5 valence electrons
- Oxygen (O) - 6 valence electrons
- Fluorine (F) - 7 valence electrons
- Neon (Ne) - 8 valence electrons
These values represent the number of electrons in the outermost energy level (valence shell) of each element.
