Well, you have the usual culprit:

Cesium (element 55)

It explodes when in contact with water, which is more noticeable than other alkali metal brothers.

ium (element 87)

The more reactive version of cesium is also radioactive!

Although we can only synthesize a small amount of it

Fluorine (Element 9)

Harmful reactive gas. Don't misunderstand fluorine, it will annoy you.

Carbon (element 6)

The fact that it is the foundation of all life on earth is crazy.

Then you will get very cool allotropes such as graphite, diamond and graphene

(Element 76)

The densest natural elements

(Element 96)

Glowing purple in the dark (SO COOL)

Also has some interesting magnetism

Did I mention that it glows in the dark?

hall (element 81)

Bad egg poison-even put arsenic on the list


Liquid metal at room temperature? Yes, please!

For some people, "hydrogen" is crazy-but hydrogen is 75% of the observable universe. That's not a lunatic. Hydrogen is normal.

However, I want to speak out about gallium (element 31).

Non-transition metals in p-blocks. Sounds boring, right?

Well, when applied to solid-state physics, it actually has some very interesting properties, as a dopant in semiconductors, and so on (gallium arsenide also has the distinction of participating in the most precise experiment I have done!)

But because of the prank, I like it!

You will find that the melting point of gallium is very low.

At room temperature, it is almost solid, but the temperature of the human body is enough to melt

You can make a spoon with a spoon made of gallium, and it will disappear when you stir the tea with it!

If you like the peiodic table, you can also check out our periodic table display with acrylic and real elements. Bring it home, it makes a good decor!
