Room No.11 Sodium-tchi

He lives in the room No.11 at the Periodic-Table-Apartment(PTA).

He is one of the alkali metal and would like to shake hands with other Little Elements.
In particular, they are in close contact with Chlorine-tchi who lives in room No.17, and sodium chloride refined by holding hands is very important to living things.

He is an essential element for many organisms and is active in neurotransmission and the like.
Sodium-tchi is also active in the human world such as sodium bicarbonate with Carbon-tchi, Oxygen-tchi, Hydrogen-tchi, sodium glutamate as a umami component, and sodium carbonate used as a detergent.

Recently, he seems to have acquired a technique to save electricity with Sulfur-tchi who lives in room No.16. That battery capable of recharging a large amount of electric power is called NaS battery, and attracts attention in recent years.

Sodium-tchi also emits a yellow color due to a flame reaction.
Therefore, yellow fireworks are thanks to him.

Room No.3 Lithium-tchi

Room No.37 Rubidium-tchi

Room No.3 Lithium-tchi

He lives in the room No.3 at the Periodic-Table-Apartment(PTA).

He is the lightest metal in your earth.
He is so soft that you can cut him easily.

He is one of the alkali metal and would like to shake hands with other Little Elements.
He is wearing the clothes imitating the electric device that you usually use.

When you roast him, he emits red light. It is called fｌame reaction.

His most important work is of course the lithium battery.
The lithium battery is very light and has high density of electric energy.
Recently, many kinds of electric devices cannot work without him.
Therefore, you have been always helped by him unless you enjoy self-sufficient lifestyle.

When two Lithium-tchi play with one Carbon-tchi(room No.6) and three Oxygen-tchi(room No.8), you call it lithium carbonate.
It is said that the lithium carbonate preparation is good for your tranquilizers.
