Alkali+Metals

=pablo and david b=

=The Alkali Metals= The alkali metals are the elements that are in group 1 of the periodic table.They are really reactive metals and they are not found naturally in nature. The only way they exist naturally in nature is as compounds.They only have one electron so they lose it often in ionic bonding. They are like all metals so they are malleable and are good conductors of heat and electricity but they are softer than most of the other metals. The alkali metals are Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. The reactivity of the alkali metals increases from the top of Group 1 to the bottom. =The Reaction Of the Alkali Metals= The alkali gas are so reactive that elements like sodium and potassium have to be stored under oil so they dont react to the moisture in the air. The metals are really light and Li, Na, and K are all less dense than water so they float but not for long until they react and explode violently. The element Celsum is so reactive that it reacts with water temperatures as low as -115 C. Francium is the most reactive element of the group. It is said that if you put a gram of francium inside a bathtub filled with water the reaction will cause the whole bathroom to explode. Francium is also the rarest element on earth.
