Hydrogen(AN: 1 / H)

History
Hydrogen was created in 1766 by ‘Henry Cavendish’ of England.
It was called ‘burning gas’ at the time because it burns intensely.
Properties and characteristics
As mentioned, hydrogen burns violently when ignited. There is even a phenomenon known as a ‘hydrogen explosion’.
Hydrogen is also the lightest of the elements and, moreover, the most abundant element in the universe.
Applications
‘Fuel cells’.
A device that generates electricity through a chemical reaction between hydrogen and oxygen. Recently used in ‘fuel cell vehicles’ (FCVs).
You can read more about hydrogen in the following article, if you like.
Helium. (AN: 2 / He)

History
Helium was discovered in 1868 by the British ‘Lockyer’ and French ‘Jansen’ while observing the sun.
At that time it had not yet been discovered on Earth, and the name ‘helium’ was taken from the Greek god Helios, the sun god.
Prosperities and characteristics
It is a non-flammable element and the second most abundant element in the universe.
However, it is an extremely rare element, as only about 0.0005% is present in the Earth’s atmosphere.
Applications
Helium gas.
The name may ring a bell with many of you.
Whether used for balloons or as a voice-altering joke toy, helium is more accessible than you might think.
Helium is explained in more detail in the following article, if you wish to read it.
Lithium (AN: 3 / Li)

Fluorine (AN: 9 / F)

History
Fluorine was discovered by the French ‘Moissan’ in 1886.
Properties and characteristics
It is a highly reactive element that reacts with ‘all elements’ except neon and helium, whereas fluorine on its own is a highly toxic and dangerous element.
However, it does not exist on its own in nature, and when it is in a form known as ‘fluoride’, it is safe to consume on a daily basis (unless consumed in very large amount).
Applications
Toothpaste.
Have you seen many toothpastes recently that say ‘contains fluoride’?
Dentists sometimes apply it directly to the teeth.
That’s because fluoride repairs the surface of the teeth.

Natrium (AN: 11 / Na)

History
Natrium was discovered by ‘Davy’ in England in 1807.
Properties and characteristics
Element so soft that, despite being a metal, it can be cut with a knife.
Incidentally, when placed in water it reacts violently, catching fire and exploding.
Natrium is therefore stored in ‘petroleum’ to prevent the reaction.
Applications
‘Salt’.
Salt, an essential part of the diet, contains Natrium.
Magnesium (AN: 12 / Mg)

History
Magnesium was discovered by ‘Davy’ in England in 1808.

Phosphorus is used on the box side, not the stick.
Long ago, there were yellow phosphorus matches, which were more flammable than today’s ones.
Sulfur (AN: 16 / S)

History
Unknown
Properties and characteristics
This is found in volcanic gases and hot spring waters.
In fact, Sulphur by itself has no odor, but when dissolved in water it becomes ‘hydrogen sulfide’ and becomes odorous.
Applications
‘Matchsticks’.
Phosphorus is a box of matches, whereas Sulphur is a matchstick. The part of the tip that catches fire contains a sulfur component.
Chlorine (AN: 17 / Cl)

History
Chlorine was discovered by the Swedish ‘Scheele’ in 1774.
Properties and characteristics
It is a bactericidal element.
It is also used in salt, together with sodium, ‘NaCl’, which you may have heard of.
