No, iodine is not a mineral sulfide. Iodine is a chemical element and essential nutrient that is commonly found in seawater and some minerals. Sulfides are a group of minerals that contain sulfur combined with another element or elements, but iodine is not classified as a mineral sulfide.
Galena is in the sulfide group of minerals.
Antimony is a metalloid element that belongs to the nitrogen group on the periodic table. It is not classified as belonging to a specific mineral group, but it is commonly found in sulfide minerals such as stibnite (antimony sulfide).
Gypsum is a common mineral that contains sulfate, which is in the form of the sulfate group (-SO4). The sulfate group is often found in minerals such as anhydrite and barite as well.
Chalcopyrite belongs to the sulfide group of minerals.

The chemical formula for rubidium sulfide is Rb2S. Rubidium is a group 1 element with a +1 charge, while sulfide is a group 16 element with a -2 charge, so two rubidium ions are needed to balance the charge of one sulfide ion.
Magnesium sulfide (MgS) is formed by the reaction of magnesium with sulfur.
The lead acetate test is used to detect the presence of the sulfhydryl (thiol) group in amino acids, particularly cysteine. When lead acetate solution is added to a sample containing a sulfhydryl group, a black precipitate of lead sulfide forms, indicating a positive test for the presence of sulfhydryl groups.
Galena is a mineral, lead suphide (PbS), and as such, it is in the group of sulfide minerals. Links can be found below to check facts and learn more.
No, garnet is not a sulfate. Garnet is a group of silicate minerals that have a similar crystal structure but different chemical compositions, typically containing aluminum, iron, magnesium, and other elements. Sulfates, on the other hand, are minerals that contain the sulfate ion (SO₄) as a fundamental part of their structure. Thus, garnet belongs to the silicate class rather than the sulfate class of minerals.
Cinnabar belongs to the group of sulfide minerals, specifically as a mercury sulfide (HgS). It is the most important ore of mercury and is characterized by its distinctive red color. Cinnabar typically forms in hydrothermal veins and can also occur in sedimentary deposits.
