A fun way to learn about elements
There is a video channel on You Tube that will feature a video about each element on the periodic table. I am featuring the video on sodium below.
Sodium is amazing
When sodium is placed in water it floats because it is lighter than water. It also reacts with water. Sodium, because it is more reactive, takes the place of of one of the hydrogen atoms in water, (HOH). The hydrogen replaced is freed and the heat energy of the reaction often ignites the hydrogen. The burning hydrogen combines with oxygen in the air releasing energy which appears to be an explosion (or is it an implosion). All I know is that when my high school companions threw a chunk of it in the river the result was water blasted 13 feet into the air.
Sodium is hazardous
One should note that the sodium attached to the remaining OH from the water molecule makes sodium hydroxide (NaOH). Sodium Hydroxide is the active ingredient in Drano which eats through fat, grease, and skin. I learned the hard way that it burned skin and ruined clothing.

Afterwards, see if you can guess how many more elements have been added since. And can you name them? Personally, I can't get the dang song out of my head.
But now watch this little four-year-old showboat put you to shame.
I'm so embarrassed.
