Oxygen

Hydrogen

Verified step by step guidance

Identify the atoms involved in the water molecule, which are hydrogen (H) and oxygen (O).

Understand the concept of electronegativity, which is the ability of an atom to attract shared electrons in a chemical bond.

Recall that oxygen is more electronegative than hydrogen. This means oxygen has a stronger tendency to attract electrons towards itself.

Consider the periodic table trends: Electronegativity increases across a period from left to right and decreases down a group. Oxygen is to the right of hydrogen in the same period, indicating higher electronegativity.

Conclude that in a water molecule, the oxygen atom has a greater pull on the shared electrons compared to the hydrogen atoms due to its higher electronegativity.
