Which of the following statements is true of the bonds in a water molecule?
A
The bonds are ionic, formed by the transfer of electrons.
B
The bonds are hydrogen bonds, formed between hydrogen and oxygen atoms within the molecule.
C
The bonds are metallic, involving a sea of delocalized electrons.
D
The bonds are covalent, formed by the sharing of electrons.
Verified step by step guidance1
Begin by understanding the types of chemical bonds: ionic, covalent, hydrogen, and metallic. Each type involves different interactions between atoms.
Ionic bonds occur when electrons are transferred from one atom to another, typically between metals and nonmetals. This results in the formation of charged ions.
Hydrogen bonds are a type of weak interaction that occurs between molecules, not within a molecule. They are typically found between hydrogen and electronegative atoms like oxygen, but not within the same molecule.
Metallic bonds involve a 'sea of electrons' that are delocalized across a lattice of metal atoms, allowing for conductivity and malleability. This is characteristic of metals, not water molecules.
Covalent bonds involve the sharing of electrons between atoms, allowing them to achieve a stable electron configuration. In a water molecule (H₂O), the oxygen atom shares electrons with two hydrogen atoms, forming covalent bonds.
