What is the chemical formula for aluminum fluoride? a) al3f b) alf c) alf3 d) alfl3

The chemical formula for aluminum flouride is C). AlF3.

Answer : The chemical formula for aluminum fluoride is

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

Hence, the chemical formula for aluminum fluoride is
