WebJun 9, 2014 · Its electron configuration would look like this Mg: 1s22s22p63s2 Now, when the magnesium cation is formed, two electrons, hence the 2 + charge of the cation, are lost by the magnesium atom. These electrons, which are called valence electrons, come from magnesium's outermost energy level. Web6.

4.7: Ions - Losing and Gaining Electrons - Chemistry …
WebDec 7, 2016 · Well, that's just because you're asking about the M g2+ ion. The 2+ charge indicates that you have lost two electrons, which means that we'd subtract two from the original tally. Another way you could do this would be to write out the electron … WebExplanation: The order is based on the tendency of the half-reaction to be reduced. Mg2+ has the highest tendency to be reduced and hence is the strongest reducing agent. Co2+ has the lowest tendency to be reduced and hence is the weakest reducing agent.
