Question

complete the paragraph to explain why water is a polar molecule. in a molecule of water, the oxygen atom shares with each hydrogen atom. oxygen also has non - bonding pairs of valence electrons. because valence electrons are more attracted to oxygens nucleus than to hydrogens nucleus, the oxygen atom has a slightly charge and the hydrogen atoms have a slightly charge.

Explanation:

In a water molecule, oxygen and hydrogen share a pair of electrons (a covalent - bond). Oxygen has 2 non - bonding pairs of valence electrons. Since oxygen is more electronegative than hydrogen, it attracts the shared electrons more strongly, giving oxygen a slightly negative charge and hydrogen a slightly positive charge, making water polar.

Answer:

In a molecule of water, the oxygen atom shares a pair of electrons with each hydrogen atom. Oxygen also has two nonbonding pairs of valence electrons. Because valence electrons are more attracted to oxygen's nucleus than to hydrogen's nucleus, the oxygen atom has a slightly negative charge and the hydrogen atoms have a slightly positive charge.
