Answer : The chemical formula for aluminum fluoride is [tex]AlF_3[/tex]
Explanation :
Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.
Ionic compound are usually formed when a metal reacts with a non-metal.
The nomenclature of ionic compounds is given by:
1. Positive ion is written first.
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
3. In case of transition metals, the oxidation state are written in roman numerals in bracket in-front of positive ions.
The given compound is, aluminum fluoride.
Aluminum fluoride is an ionic compound because aluminum element is a metal and fluorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
The charge on aluminum is (+3) and the the charge on fluorine is (-1). Both combine with the an ionic bond by the criss-cross method. Thus, the formula of the compound potassium chloride will be [tex]AlF_3[/tex]
Hence, the chemical formula for aluminum fluoride is [tex]AlF_3[/tex]
