* Atomic Number: 9

* This means fluorine has 9 protons in its nucleus.

* Atomic Mass: Approximately 19 (more precisely 18.9984032 amu)

* This means fluorine has 10 neutrons in its nucleus (19 - 9 = 10).

* Electrons: 9

* Since atoms are electrically neutral, fluorine also has 9 electrons orbiting its nucleus.

Important Note: The number of neutrons in fluorine can vary slightly, leading to isotopes. The most common isotope of fluorine has 10 neutrons, but there are rare isotopes with different neutron counts.

Visual Representation:

Imagine a tiny solar system.

* Nucleus (Sun): Contains 9 protons and 10 neutrons (for the most common isotope).

* Electrons (Planets): 9 electrons orbit the nucleus in shells or energy levels.
