Question

part b
the unequal sharing of electrons by the polar covalent bonds of a water molecule causes the atoms to have slight charges. which atoms are slightly negative and which are slightly positive?
oxygen and hydrogen atoms are both slightly positive.
oxygen atoms are slightly positive, hydrogen atoms are slightly negative.
oxygen and hydrogen atoms are both slightly negative.
oxygen atoms are slightly negative, hydrogen atoms are slightly positive.

Explanation:

Oxygen is more electronegative than hydrogen in a water - molecule. In a polar covalent bond of water, oxygen attracts the shared electrons more strongly, making it slightly negative and hydrogen slightly positive due to the unequal sharing of electrons.

Answer:

Oxygen atoms are slightly negative, hydrogen atoms are slightly positive.
