Question

a water molecule consists of a central oxygen atom to which two hydrogen atoms are connected with ------- bonds.

a. metallic
b. ionic
c. covalent
d. coordination
clear my choice

Explanation:

In a water molecule ($H_2O$), oxygen and hydrogen atoms share electrons to achieve stable electron - configurations. Covalent bonds involve the sharing of electron pairs between atoms. Metallic bonds are in metals, ionic bonds are between ions, and coordination bonds are a special type of covalent bond with a donor - acceptor relationship which is not the case here.

Answer:

C. covalent
