Question

write out the correct formula using oxidation number rules then write out the compound name of 

1. Hydrogen and Sulfur

2. Lithium and Flourine 

3. Silicon and Oxygen 

4. Nitrogen and Hydrogen

anonymous · Answer

1 Li+  + 1 F- = LiF   lithium fluoride

is how I think they want you to do it. Li+ loses its valence electron
to Fluorine's outer shell, and they form an ionic salt. 

Other compounds are likely to be H2S, SiO2 and NHx, which I'm not sure of.

Good luck.

@douglaswinslowcopper is right, and the last answer is NH3

anonymous · Answer

And you have to name them too...
so... dihydrogen sulfide, lithium flouride, silicon dioxide, and ammonia (nitrogen trihydride)

gebooors · Answer

Nitrogen is more electronegative than Hydrogen.
So it should be H3N and triHydrogen Nitride
