The alkali metals (lithium, sodium, potassium, rubidium, caesium, and francium) are the most homogeneous column of elements in the periodic table, exhibiting very clear periodic trends. All of them are soft and extremely reactive metals, readily giving up their sole valence electron to form cations. Their history spans over centuries, from the ancient use of sodium and potassium salts to the ongoing attempts to make the elusive element 119. All five stable alkali metals have important applications, with sodium and potassium being essential elements for life.
Support, pending assurances that 119 will be expanded when it's discovered within the next few years :D - one can hope the table will go past 118! ♫

Box includes 8 articles but says 7 at the top. Something weird going on with Ununennius? I noticed ot was not in the table on the alkali metals artcle like the rest?

Yes, my mistake, I miscounted. Ununennium is not on the table in the main article because it hasn't been discovered yet. Hopefully it will be in the next few years, upon which we will make the necessary updates! ^_^

Done Didn't include element 119, since it's not yet been discovered (and chemical investigation after that will probably have to wait another decade or so).
