What does the position of lithium (li) on the periodic table tell you about its tendency to react with other elements?

It is in the first column, so it tends to lose one electron.

Explanation:

(I just answered this question on my own as I couldn't find it on :/)

Anyways,

It is clear the lithium is in the first column, not the second row, so that already eliminates two of the four possible answers.

Lithium has 3 protons and 3 electrons. Meanwhile, elements further to the right of this element tend to have increasingly more protons/electrons. To become a stable bond, there must be a total of 8 electrons.

For example,

while lithium has 3 electrons, Nitrogen has 7. It needs one more to become stable. So Lithium will bond with Nitrogen and give it one of it's electrons for a total of 8.

answer: he got 23
