the answer is D. A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion 
because magnesium only has 2 valence electrons, and it would be easier to lose electrons rather gain. 
i just took the test, its right.

Answer:
total current = 12.417 A 
so it will not fuse as current is less than 15 A 
Explanation:
given data 
toaster = 1140-W
blender = 270-W
lamp = 80-W 
voltage = 120 V 
solution
we know that current is express as
current = power ÷ voltage   ......................1
here voltage is same in all three device 
so 
current by toaster is 
I = 
I = 9.5 A
and 
current by blender
I = 
I = 2.25 A
and 
current by lamp is 
I = 
I = 0.667 A 
so here device in parallel so 
total current is = 9.5 A + 2.25 A + 0.667 A 
total current = 12.417 A 
so it will not fuse as current is less than 15 A
