Alkaline Metals

What is an alkaline metal? 

Alkali metal is any of the metals that make up the first column of the periodic table. te six chemical elements that make up the first row are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The reason for their placing on the periodic table is because the one-electron that is placed in the outer sell of all the alkaline metals means the alkali metals are extremely reactive and can react with water, with the heavier alkali metals reacting more overwhelmingly than the lighter ones. 

What reaction did we create? 

For our experiment, we wanted to test the alkaline metals in the water to see what the reaction would look like. For our experiment we used Lithium and sodium, te lithium fizzed for a moment before sparking up and creating a small amount of smoke this is because the lithium reacted with the oxygen in the water leaving hydrogen left over causing it to create hydrogen gas. however the sodium had a different reaction when placed in water, the sodium smoked for a few seconds before catching fire then exploding. 


Products & Reactants 

Sodium (Na) + Water = Sodium oxide + hydrogen gas       
(2Na + h2O = Na2O +h2)
