They all have. one electron in their outer shell, making them. very reactive. They are low density. As you go down the group, they become more reactive. They get bigger which makes it easier to lose an electron as it is further away from nucleus. Alkali metals reacting with water: lithium hydroxide 2 LIOH + hydroxide + hydrogen H₂ Fr sodium water →ngaroxide + hydrogen. + 2+120 →2 NaOH + H₂ Potassium potassium + water → hydroxide + hydrogen 2K H₂ t 2H202KOH +
