Question 21 • $2526: SEM 1: 2003310: Physical Science: NEW

Which statement correctly describes the electrons in a water molecule?

Answer
A
Electrons are pulled closer to the hydrogen atoms.
B
Electrons are pulled closer to the oxygen atom.
C
Electrons are located inside the nucleus of the hydrogen atoms.
D
Electrons are located inside the nucleus of the oxygen atoms.

Explanation

Oxygen attracts shared electrons more strongly than hydrogen does because oxygen is more electronegative. So the electrons in each O–H bond spend more time closer to the oxygen atom. The nuclei contain protons and neutrons, not electrons.
