Name the elements present in the compound calcium sulphide?
The compound calcium sulfide is made up of calcium (Ca) and sulfur (S) elements.
Is calcium an element compound or mixture?
Calcium is an element. It is a pure substance made up of only one type of atom, specifically calcium atoms.
Calcium Sulfide formula?
CaS Because Calcium has 2 electrons in its outer shell- so it needs to get rid of those (Ca2+) Sulfur has 6 electrons in its outer shell- so it needs 2 more to have a full outer shell (S2-)
What two elements make up calcium?
Calcium is an element itself. It has the chemical symbol Ca and atomic number 20.
Is sulfide an element or a compound?
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.

What charge does sulfide have?
The charge that sulphide has will depend in its state. Sulphide in itself does not have any charge but sulphide ion has a negative charge.
