Exceptions and Amazing Facts about Chemistry
Chemistry is an entrancing science loaded
with exceptions and uncommon incidental
data although there are many interesting and
amazing facts in it. In this article, I'm noting
down 18 facts about Chemistry which includes
exceptions and amazing statements.

1. Maximum density of water at 4oC
First of all, water. Water, which is the basic
component without which we can not survive,
contracts when it is heated from 1-4oC and
then it expands from 4oC which means that
water has maximum density at 4oC.

2. More about water
In the event that you pour down a bunch of
salt into a full glass of water, the water level
will really go down as opposed to flooding
the glass.

Also, on the off chance that you blend a liter
of liquor and a liter of water, the complete
volume of the fluid mixture will be short of
one liter.

3. Liquid metals
The main strong components that accept fluid
structure at room temperature are bromine
(At. No. 35) and mercury (At. No. 80).

Nonetheless, gallium (At. No. 31) and Cesium (At. No. 55) are also semi liquids at room temperature. Do you know that gallium melts when you put gallium on your hand by absorbing your body heat since its melting point is below our normal body temperature and you can dissolve a spoon in gallium liquid.
4. A whole large rubber tire, a single molecule!!!!😟😟😟
Most of the molecules are microscopic in size but the vulcanized tire, is technically a giant and polymerized molecule which is all made of large polymereric chains that have been crosslinked together with covalent bonds.
5. Different forms of a substance
An element or compound takes numerous
forms of existence. For instance, diamond,
graphite and fullerene are allotropes of
carbon. Do you know the football-shaped carbon cluster C60 (Fullerene) has been called ‘the most beautiful molecule’.
Do you know that a company called, Designer Carbon Materials
sold 200 micrograms of pure endohedral fullerenes for $33,400!!!

Radioactive substances Glow
They are those substance whose nucleus is not stable and disintegrate producing numerous amount of radiation. Numerous radioactive components really glow in dark (Phosphorescence).
7. Lightning
produces Ozone
Lightning strikes produce oxone, which
produces a characteristic smell after lightning.
produces a characteristic smell after lightning.
Ozone, the triple oxygen atom that demonstrations like a defensive stratospheric cover against bright beams, is made in nature
by lightning. When it strikes, the lightning splits oxygen atoms in the air into radicals which change into ozone. The smell of ozone is sharp, frequently portrayed as like that of chlorine.
This is the reason you get that "perfect" smell sensation after a lightning.

8. Gold
and Copper
The main two non-gleaming metals are gold
and copper. these two metals ingest blue
and violet light, leaving yellow light. It's significant here that copper is likewise the main metal that is normally antibacterial.

The liquid and solid forms of oxygen are
blue though the gaseous oxygen is colourless.

10. Glass
a liquid!!!!
Glass is actually a super cooled liquid and it flows very, very slowly. you can check it by comparing the thickness of the upper and lower portions of a glass window of very very old monuments

Hydrogen, Only substance without Neutron
Protium, the most abundant isotope of
Hydrogen is the only substance which has
no neutron though the other two isotopes,
deuterium and tritium have neutrons.

12. Super
fluid Helium can climb on walls
Super fluid helium defies gravity and it can climb on walls.
A remarkable transition occurs in the properties of liquid helium at the temperature 2.17K (very close to absolute zero), called the “lambda point” for helium. Part of the liquid becomes a “superfluid”, a zeroviscosity fluid which will move rapidly through any pore in the apparatus.
13. Most
abundant elements
Hydrogen is the most plentiful component known to man, while oxygen is the most abundant component (about 49.5%) in the earth's atmosphere, crust, and seas . Aluminium is the most abundant metal in the earth's crust.
14. HF
Hydrofluoric acid is corrosive to the point that it will disintegrate glass. Despite the fact that it is destructive, hydrofluoric acid is viewed as a 'powerless corrosive'.
15.
Astatine, Rarest Element
Astatine (At. No. 85) is a radioactive element and it is the rarest naturally-occurring element in the earth's crust . Only about 28g of astatine is present in the entire crust.
The human body contains enough carbon to
give 'lead' (which is truly graphite) for around
9,000 pencils.

16. The
Red Planet, Mars
Mars is regarded as Red Planet because it appears in the sky as an orange-red star. It is red in color since its surface contains a ton of iron oxide or rust.
17.
Acidic and basic stings
Honey bee stings are acidic while wasp
stings are basic.
stings are basic.
18. Our
body is full of carbon pencils!!!
Our body has enough graphite, a good conductor and an isotope of carbon, inside of it to produce roughly 9,000 pencils!!!! Really amazing na???
