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.
the decay of the neutrons in the nucleus of the atom
Answer:
CaO, CaF2, or CaCl2
Explanation:
In an ionic compound, the charges need to balance out. This is the only set of compounds that fits this criteria.
I'll try to explain this in the simplest way I've learned it.
What the last column basically meant was that if the second word of the compound has a negative ion charge
and contains oxygen it will give the the compound a name ending with -ate
