esulfur burns easily .Iron is attracted by magnets .the mineral made by sulfur and iron ,but it does not burn and it is not attr
vladimir2022 [97]
The mineral is Iron Sulphide. It is not a mixture, but a compound. A mixture is when two substances are together, but not chemically bonded. For example, if I add food colouring to water, I have made a mixture because the food colouring has not chemically bonded to the water. If I react Iron with Suphur, the resulting substance is a compound. The resulting mineral will not burn or be magnetic because the compound has different properties to the elements themselves. For example, chlorine gas is toxic and sodium reacts violently with water, but sodium chloride is table salt, nor toxic nor explosive. Hope this helps

If you put to the electrons and hydrogen making it a negative charge does that make it stable or unstable
Romashka-Z-Leto [24]

I'm pretty sure it would make it unstable, hydrogen only has one proton thus having the ability to stabilize one electron, adding another electron would most likely make the atom reactive to any positively charged atom to loose this extra electron.
