Ionic bonds
D
Metallic bonds
Verified step by step guidance1
Understand the types of bonds: Covalent bonds involve sharing electrons between atoms, ionic bonds involve transfer of electrons, metallic bonds involve a 'sea of electrons' shared among metal atoms, and hydrogen bonds are weak attractions between a hydrogen atom in one molecule and an electronegative atom in another.
Identify the nature of water molecules: Water (H₂O) is a polar molecule with a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
Recognize the interaction between water molecules: The partial positive charge on the hydrogen atom of one water molecule is attracted to the partial negative charge on the oxygen atom of a neighboring water molecule.
Determine the type of bond formed: This attraction between the hydrogen atom of one water molecule and the oxygen atom of another is known as a hydrogen bond.
Conclude that water molecules form hydrogen bonds with surrounding water molecules, which is crucial for many of water's unique properties, such as its high boiling point and surface tension.
