Naming compounds

SF(sub)2

would if be just sulfur fluoride

same goes with SF (sub)6

Sulfur Fluoride?

sulfur(II) fluoride or sulfur difluoride.

sulfur(VI) fluoride or sulfur hexafluoride.

What if it's Li(sub)3 N

would it be....
trilithium nitride? no?
Lithium nitride?

Is there a website on rules for naming compounds?

I think either would be correct. I call it lithium nitride. Since lithium has ONLY the +1 oxidation state, it isn't necessary to denote that (as in lithium(I) nitride) and I don't think it's necessary to say trilithium for the same reason.

To name compounds like SF2 and SF6, you need to consider the valence or oxidation states of the elements involved. Here's how you can determine the names:

1. SF2: Start by identifying the chemical symbols in the compound. "S" represents sulfur, and "F" represents fluorine. The subscript "2" indicates that there are two fluorine atoms bonded to one sulfur atom.

To name this compound, you need to indicate the oxidation state of sulfur using Roman numerals in parentheses after the name. Sulfur can have multiple oxidation states, so you need to determine which one it has in SF2. In this case, sulfur is in the +2 oxidation state.

The correct name for SF2 is Sulfur(II) fluoride.

2. SF6: Again, identify the symbols in the compound. "S" represents sulfur, and "F" represents fluorine. The subscript "6" indicates that there are six fluorine atoms bonded to one sulfur atom.

Similarly, you need to indicate the oxidation state of sulfur. In this case, sulfur is in the +6 oxidation state.

The correct name for SF6 is Sulfur(VI) fluoride.

Remember, when naming compounds, it is crucial to indicate the oxidation state of transition metals and nonmetals that can have multiple oxidation states.
