A magnesium atom has 12 elect. When it reacts, it loses 2 electrons. How does this loss make magnesium stable



Answer:
According to the octet rule that says that all elements atoms are most stable in the octet structure ; to have 8 electrons in the last orbit, then when we look to the Mg, we find its atomic structure is : k=2, L=8 , M=2, so it loses the two electrons of the L orbit so that it can turn to the octet structure in which state it becomes most stable.
I hope you could find your answer...
Because it now has the electron arrangement of neon, an inert gas.
