Question

which atom loses electron when mg combines with o2?​

Answer 1

Answer:

Magnesium loses two electrons to form Mg2+, and oxygen gains two electrons to form O2-. The attractive force between the oppositely charged ions is what holds the molecule together.Nov 25, 2010

Magnesium (Mg): 1.2

Hydrogen (H): 2.1

Chlorine (Cl): 3.0

Answer 2

Answer:

Mg (Magnesium)

Explanation:

As, Mg is highly electropositive element and it is also a metal and metal has the tendency to lose electrons.

So in this case the electronic configuration of Mg is [Ne]3s2 and that of O2 is [He]2s2 2p4.

So Mg can loss 2 electrons to combine with Oxygen that it(O2) gains 2 electrons.
