Question

Calcium sulfide (\[CaS\]) exhibit what type of bond \[?\]

Answer 1

Hint: To find the type of bond that forms between two elements we need to compare the electronegativities of the elements. Generally, the large differences in electronegativity result in ionic bonds and the smaller differences in electronegativity result in covalent bonds. Also, the compounds with the high melting point are consistent as an ionic solid.

Complete answer:
Chemical bonds are forces that hold atoms together to make compounds. Chemical bonds are generally divided into four types of bonds which are essential for life to exist. They are Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions.
We know that calcium sulfide is non-molecular and has very high melting points. The bond is formed between \[C{a^{2 + }}\] and \[{S^{2 - }}\] ions give the same structure as is observed in \[NaCl\] (Sodium chloride). We know that \[NaCl\] exhibits strong ionic bonds.
Hence Calcium sulfide (\[CaS\]) exhibits an ionic bond.

Additional information: Primary bonds are formed when the bonding process involves a transfer or sharing of electrons. Secondary bonds are formed from the subtle attraction forces between positive and negative charges.
Covalent bonds are two types, polar and nonpolar bonds. Whereas hydrogen bonds are two types, intramolecular (chemical bonds) and intermolecular hydrogen bonds.

Note:
Covalent bonds form between two nonmetal atoms of similar electronegativities and are formed by sharing a pair of electrons between two atoms or molecules. An Ionic bond is formed when an electron (or electrons) exchange between a nonmetal and a metal. Hydrogen bonds formed by dipole-dipole intermolecular attraction (weak electrostatic attraction) between hydrogen atoms and an electronegative atom.
