Simple answer- metal + non metal gives an ionic compound.
More technical answer the difference in electronegativity of 1.58 between Ca (EN 1.00) and S (EN 2.58) indicates a compound that is ionic (although on most measures it is borderline). However it is colorless with a rock salt crystal structure, both indicative of ionic nature.

What is Ca2 and S2- ionic formula?
The ionic formula for Ca2+ and S2- is CaS, which is calcium sulfide. In this compound, calcium donates two electrons to sulfur, forming a ionic bond between the two elements.
What is the ionic equation of cacl2 plus na2s equals cas plus nacl?
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
What is the most accurate name for the Ionic compound CaS?
Calcium sulfide.
Is CaS ionic pr covalent?
CaS is an ionic compound. Calcium (Ca) is a metal and sulfur (S) is a nonmetal, so they bond together through ionic bonding where electrons are transferred from calcium to sulfur, creating charged ions that are held together by electrostatic forces.
Is CaS a covalent bond?
No, CaS (calcium sulfide) is not a covalent bond. It is an ionic bond, formed between calcium (a metal) and sulfur (a nonmetal) resulting in the transfer of electrons from calcium to sulfur.

Is CaS a covalent compound?
Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
Is CaS a covalent bond?
No, CaS (calcium sulfide) is not a covalent bond. It is an ionic bond, formed between calcium (a metal) and sulfur (a nonmetal) resulting in the transfer of electrons from calcium to sulfur.
What is the ionic bond formula between calcium and sulfur?
The ionic bond formula between calcium and sulfur is CaS, where calcium loses 2 electrons to form Ca2+ cation and sulfur gains 2 electrons to form S2- anion. This results in the formation of an ionic compound called calcium sulfide.
What is the ionic compound formula between calcium and sulfur?
The ionic compound formed between calcium and sulfur is calcium sulfide, with the chemical formula CaS. In this compound, calcium has a 2+ charge and sulfur has a 2- charge, resulting in a neutral combination.
What is compound Ca plus S?
When calcium (Ca) reacts with sulfur (S), they form calcium sulfide (CaS), a compound where one calcium ion is bonded to one sulfur ion through an ionic bond. The chemical formula for this compound is CaS.
What are the formulas for the binary ionic compounds formed between calcium and sulfur?
The binary ionic compound formed between calcium and sulfur is calcium sulfide. The formula for calcium sulfide is CaS. The charges on calcium and sulfur ions are +2 and -2 respectively, so they combine in a 1:1 ratio to form a neutral compound.
Which of the following would you expect to be a molecule and which would you expect to be part of an ionic solid CO HCl KF MgO SO CaS KCl NaI?
A very common example of an ionic compound is salt. The sodium (Na) and chlorine (Cl) atoms in it form what is called a crystal lattice. It organises atoms into squares, and then boxes and layers the boxes on one another over and over to make a lattice-like structure.
What is the ionic formula for calcium sulfide?
The chemical formula starts out with the two ions, the calcium and sulfide ions. Calcium's ion is Ca2+, while the sulfide ion is S2-. Because the net ionic charge of a compound is zero, only one of each atom is needed to create calcium sulfide, which will be CaS.
