Answer:
AlF3
Explanation:
Aluminum fluoride (AlF3) is an inorganic compound in which aluminum and fluoride has ionic bond between each other.
Aluminum ( atomic number - 13) has 3 valence electrons and can lose 3 electrons to get a stable configuration while fluorine (atomic number - 9) can gain one electron to make a stable configuration. So in order to attain a stable configuration one aluminum (Al) atom form ionic bond with three fluorine atoms and form AlF3.
Hence, the chemical formula between Al and F is AlF3.
