Question

Which of these in each pair is more likely to LOSE an Electron?
Li or K

Al or C

Na or Mg

Answer 1

Answer:

The most common reducing agents are metals, for they tend to lose electrons in their reactions with nonmetals. The most common oxidizing agents are halogens—such as fluorine (F2), chlorine (Cl2), and bromine (Br2)—and certain oxy anions, such as the permanganate ion (MnO4−) and the dichromate ion (Cr2O72−).

Answer 2

Answer:

Na or Mg is the correct option.

They have the largest atomic size as compared to the other options. Hence, the effective neuclear charge attracting the electrons would be relatively lesser, making it easier to lose electrons.
