What is the correct name for #MgF_2#?

Answer 1

Magnesium (II) fluoride or simply magnesium fluoride

This type of simple salt, which consists of just one anion (negatively charged species) and one cation (positively charged species), is known by the nomenclature provided by

#M\e\t\al# #(char\g\e)# #anion#

Given the compound, we can infer that the metal is magnesium, the anion is fluoride, and the metal's charge is

#MgF_2 rarr Mg^(+2) + 2F^(-)#

two, or II, in order to construct the name as

magnesium fluoride (II).

However, we can leave out the charge because magnesium is typically found as a metal (charge 0) or as a salt (charge II).

Fluoride magnesium

isn't incorrect.
