If you express your answer as a chemical equation with all forms given, you would get:
Mg+(g) + e- -> Mg (g)
O because it is a 2-
MgCl2
Be is least reactive its outermost orbital 2s is completely filled so its electron affinity is almost zero.
Yes, it is correct.
MgCl2 plus 2H20 produces Mg(OH)2 plus 2HCl
Generally, electron affinity increases (becomes less negative) in groups/families moving from top to bottom.
O because it is a 2-
MgO2
Chlorine and Argon respectively.
MgO2
MgCl2
The Mg atom has more electron than the Mg+2 ion.
Be is least reactive its outermost orbital 2s is completely filled so its electron affinity is almost zero.
mg + CuCl2 + MgCl2 + Cu Mg + Cu^+2 = Mg^+2 + Cu
because it is cool
Yes, it is correct.
NO3-
