Hi everyone! Welcome to another post this week for science we did an experiment on Alkaline Metals. For the experiment, we mixed water with some alkaline metals so that we could observe how the metals reacted to the water.
What is an Alkaline Metal?
An alkaline metal is very reactive and explosive when mixed with water. There are a total of 6 alkali metals and are found on the last left column of the periodic table.
What reaction did we do yesterday?
Yesterday we used Lithium and Sodium to observe how they reacted to the warm water. A chemical reaction that was used for this was Sodium + Water 🠂 Sodium oxide + Hydrogen.
(2Na + H2O 🠂 Na20 + H2)
Observations: Why did the metal react this way?
When the metal (Sodium) was put inside the water the metal lit on fire, the fire wasn't big. The metal lit on fire because of how much the sodium was attracted to the oxygen, seeing that the chemical name for water is H20. When the Sodium was reacting with the oxygen it was leaving behind hydrogen gas that created the explosion.
Why do these metal react this way?
It only has 1 electron which is why it is highly reactive.
