Tin(II) fluoride or stannous fluoride

Answer 2

Answer : The correct name of $SnF_2$ is, tin(II) fluoride.

Explanation :

$SnF_2$ is an ionic compound because tin 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 nomenclature of ionic compounds is given by:

• Positive ion is named first.
• The negative ion is named next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
• In case of transition metals, the oxidation state are written in roman numerals in bracket in-front of positive ions.

The charge on tin is (+2) and the the charge on fluoride is (-1).

Hence, the correct name of $SnF_2$ is, tin(II) fluoride.
