# of electrons

Answer 1

Here is the information for the element Fluorine (F):

- **Atomic Number**: 9
- **Atomic Mass**: 18.998
- **Number of Protons**: 9
- **Number of Neutrons**: 10 (calculated as: Atomic mass (approximately 19) - Atomic number (9) = 10)
- **Number of Electrons**: 9 (in a neutral atom, the number of electrons equals the number of protons)

So, to summarize:

- Atomic Number: 9
- Atomic Mass: 18.998
- Number of Protons: 9
- Number of Neutrons: 10
- Number of Electrons: 9
