Because they typically only have one valence election, and the first row is labeled “1.”

Step-by-step explanation:

All atoms naturally want to have a completely full outermost shell of electrons.Howevee, elements in that first column of the periodic table all have one electron in their outermost shell. ..."since the alkali metals only have one valence electron,they typically achieve this state by giving up that electron.

I hope it's helpful!
