Mercuryfluoride
The formula given is for mercury (I) fluoride, also known as mercurous fluoride.
That would be Mercury(II) fluoride. Idiot.
HgF
The empirical formula for Hg₂F₂ is HgF. This is because the empirical formula represents the simplest whole-number ratio of atoms in a compound.
The compound name for SiI4 is tetrasilane.

WARNING=Never ever try this at home. This reaction should be done in minute quantities, and outside the home.When the orange poisonous compound Mercury(II) Oxide is heated, it produces poisonous vapours of Mercury (which become liquid after reaching the room temperature) and Oxygen. Here is the balanced equation for this=2 HgO ---Δ---> 2 Hg + O2
18k hgf would stand for 18k heavy gold filled ( not solid gold )
It could mean 18 karat "hollow gold filled". I'm not familiar with a manufacturer's hallmark that is "HGF".
"14k HGF" typically refers to a type of gold jewelry or item that is made from 14 karat gold and may include the initials "HGF," which could stand for a brand, designer, or manufacturer. The "14k" indicates that the gold is 58.3% pure, with the remaining 41.7% being other metals, which is common in jewelry for durability and color. If "HGF" has a specific context or meaning beyond that, it may require additional information to clarify.
