Question

Indicate whether each of the following is covalent or ionic.

A) Cu2O
B) SiCl4 covalent
C) H2O
D) BaS
E) CS2

Answer 1

Compounds A) Cu2O and D) BaS are ionic, while B) SiCl4, C) H2O, and E) CS2 are covalent. Ionic compounds are associated with metals and nonmetals, while covalent compounds generally involve nonmetals only.

Step-by-step explanation:

The classification of compounds as ionic or covalent depends on the types of elements involved and the nature of the bond between them. Typically, ionic bonds form between metals and nonmetals, and covalent bonds form between nonmetals.

• A) Cu2O: Ionic - Composed of Cu+ and O2- ions.
• B) SiCl4: Covalent - Involves sharing of electrons between Silicon (Si) and Chlorine (Cl).
• C) H2O: Covalent - Oxygen and Hydrogen share electrons.
• D) BaS: Ionic - Consists of Ba2+ and S2- ions.
• E) CS2: Covalent - Carbon and Sulfur share electrons.
