What does the position of lithium on the periodic table tell you about its tendency to react with other elements? a) it is in the second row, so it tends to gain two electrons. b) it is in the second row, so it tends to lose two electrons. c) it is in the first column, so it tends to lose one electron. d) it is in the first column, so it tends to gain one electron.

Lithium is part of the alkali metals group or group 1 where each element has 1 valence electron in their outer shell. Due to this fact, it is easier to lose one electron and donate it to achieve octet or stability. Lithium is in the second row so it is harder to lose an electron as it's least reactive. The best answer is then C. It is in the first column, so it tends to lose one electron.
