sulfur
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.
yes
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.
The formula for stannic sulfate is Sn(SO4)2, where Sn represents the element tin and SO4 represents the sulfate group. The compound is made up of one tin atom bonded to two sulfate ions.
I believe it is group 11 since it is a group in the transition metal class, and transition metals form ions with color.
