Electrons are shared or swapped between atoms.
The elements will react and will form iron sulfide, which is a compound.
Gold is an element. It can be mixed with other elements to form compounds, but gold itself is a pure substance, not a mixture or a compound of elements.
A compound. (Could also be a mixture depending on if they are fused together or mixed)
It is neither an element not a compound. Steel is an alloy. An alloy is a mixture of a metal and another element. In the case of steel, it is principally iron (an element), with about 0.2% to 2,0% carbon ( an element), mixed in. Other elements can be mixed in , e.g. chromium to form Stainless Steel, or Tungsten to form hard wearing steel.
A sufide is an anion form of the element sulfur. It can form compounds if it combines with other elements. Sulfide on it's own is not a compound, you need a prefix to that like Hydrogen Sulphide. Do not get this mixed up with a sulfate; you can get copper sulphate but not copper sulfide.
The elements will react and will form iron sulfide, which is a compound.
iron is found in mixed form with other elements in a compound, mainly it is found as iron oxide
iron is found in mixed form with other elements in a compound, mainly it is found as iron oxide
Gold is an element. It can be mixed with other elements to form compounds, but gold itself is a pure substance, not a mixture or a compound of elements.
Elements combine to form chemical compounds.
A compound. (Could also be a mixture depending on if they are fused together or mixed)
the properties of a compound are not the same as the elements that form them.
Because the elements can combine in many ways to form compounds, and compounds can be mixed in many differed ways. Moreover, some elements occur in different forms. The elements carbon and hydrogen alone combine for form thousands of compounds.
a compound
After a chemical reaction two elements form a chemical compound.
Elements combine together by chemical bonding to form compounds.
No, when two elements join chemically to form a compound the product is neutral.
