The compound HgF is called mercury(I) fluoride.
The GCF is 27.
18k hgf would stand for 18k heavy gold filled ( not solid gold )
The compound with the formula HgF is mercury(I) fluoride.
The empirical formula for Hg₂F₂ is HgF. This is because the empirical formula represents the simplest whole-number ratio of atoms in a compound.
It could mean 18 karat "hollow gold filled". I'm not familiar with a manufacturer's hallmark that is "HGF".
