Sodium Na

Sodium - the salt in the soup of the periodic table, is available in abundance on earth and in the ocean and is the fifth most abundant metal on earth. It is contained in various natural and synthetic products used in everyday life. And at the moment scientists are intensively researching sodium-oxygen batteries as new energy storage devices. To the article about sodium on the Fascination Chemistry website.

What happens to sodium when you throw it in water? This is shown in a YouTube video from chemistry - simpleclub.

Here is a video on sodium from the Periodic Videos series

You can listen to sodium in two and a half minutes on the Deutschlandfunk Kultur podcast.

Sodium belongs to group 1 of the alkali elements.

Alkali and alkaline earth elements

The elements of the 1st main group of the periodic table are called alkali elements.

The alkali elements or alkali metals include lithium, sodium, potassium, rubidium, cesium, and francium. Together with hydrogen, these form the 1st main group of the periodic table. Hydrogen is not one of the alkali metals because it has completely different properties under standard conditions, i.e. under normal pressure and room temperature.

The elements of the 2nd main group of the periodic table are called alkaline earth elements. These include beryllium, magnesium, calcium, strontium, barium, and radium.
