Question

lets quickly review the differences between covalent bonds and hydrogen bonds. drag and drop each characteristic to show which type of bond it best describes. covalent bond hydrogen bond holds the atoms in a single water molecule together formed when two atoms share electrons formed from an attraction between a partial positive charge and a partial negative charge holds different water molecules together

Explanation:

To solve this, we recall the definitions of covalent and hydrogen bonds:

• Covalent Bond: Formed when atoms share electrons (intramolecular, holds atoms in a molecule together). Also, in a water molecule (H₂O), the O - H bonds are covalent, so it "holds the atoms in a single water molecule together" and is "formed when two atoms share electrons".
• Hydrogen Bond: An intermolecular force (between molecules) formed from the attraction between a partial positive charge (on H of one water molecule) and a partial negative charge (on O of another water molecule). It "holds different water molecules together" and is "formed from an attraction between a partial positive charge and a partial negative charge".

Covalent Bond characteristics:

• "holds the atoms in a single water molecule together" (covalent bonds hold atoms within a molecule, like in H₂O, the O - H bonds are covalent).
• "formed when two atoms share electrons" (definition of a covalent bond: electron - sharing between atoms).

Hydrogen Bond characteristics:

• "formed from an attraction between a partial positive charge and a partial negative charge" (hydrogen bonds occur between a partially positive H and a partially negative atom like O, N, F in another molecule).
• "holds different water molecules together" (hydrogen bonds are the intermolecular forces that attract water molecules to each other, causing cohesion).

Answer:

Covalent Bond:

• holds the atoms in a single water molecule together
• formed when two atoms share electrons

Hydrogen Bond:

• formed from an attraction between a partial positive charge and a partial negative charge
• holds different water molecules together
