Question

here we see the valence shells of oxygen and magnesium. how will the electrons react to make a stable product? a 1 electron will move from oxygen to magnesium. b 2 electrons will move from oxygen to magnesium. c 1 electron will move from magnesium to oxygen. d 2 electrons will move from magnesium to oxygen. oxygen atom (o)

Explanation:

Magnesium (Mg) is a metal with 2 valence electrons, and oxygen (O) is a non - metal with 6 valence electrons. To achieve a stable electron configuration (octet rule), magnesium will lose its 2 valence electrons, and oxygen will gain these 2 electrons. So 2 electrons will move from magnesium to oxygen. Option A and B are wrong because electrons move from metal (magnesium) to non - metal (oxygen), not the other way around. Option C is wrong because magnesium needs to lose 2 electrons, not 1.

Answer:

D. 2 electrons will move from magnesium to oxygen.
