Chemistry
Chemistry is a branch of science that deals with the composition,
structure, properties, and reactions of matter. It involves the study of the
behavior and properties of all types of substances, including atoms, molecules,
and ions.
Chemistry is a fundamental science that plays a crucial role in our
daily lives. It helps us understand the nature of matter, the behavior of
substances in different environments, and the chemical reactions that underlie
the processes of life, technology, and industry.
Chemistry has several sub-disciplines, including organic chemistry,
inorganic chemistry, analytical chemistry, physical chemistry, and
biochemistry. Each of these sub-disciplines focuses on different aspects of
matter and its properties.
Chemistry facts
Here are some fun and interesting chemistry facts:
1. The only letter not found in the periodic table is
"J".
2. Helium is the only element that was discovered in
space before it was found on Earth.
3. If you pour sulfuric acid on sugar, it creates a
black, carbon-like substance that can be used to create fake wounds for movies
and TV shows.
4. The most explosive chemical known to man is the
compound known as azidoazide azide.
5. The element with the highest melting point is
tungsten, which melts at 3422 degrees Celsius.
6. The only two non-silvery metals are gold and copper.
7. The chemical symbol for table salt (sodium chloride)
is NaCl. This stands for sodium (Na) and chloride (Cl).
8. If you mix bleach and ammonia together, it creates a
toxic gas that can be deadly.
9. Diamonds are made of pure carbon.
10. The smell of freshly cut grass is actually caused by a
chemical reaction that releases a gas called "green leaf volatiles".
11. The word "chemistry" comes from the Arabic
word "al-kimia", which means "the art of transformation".
12. The most common element in the universe is hydrogen.
13. The only liquid metal is mercury.
14. The element mercury is toxic and can cause damage to
the nervous system, which is why it's important to handle it with care.
15. Carbon dioxide is the gas that we exhale when we
breathe out.
16. The world's largest crystal, found in a Mexican cave,
is as big as a house and weighs approximately 55 tons.
17. The rarest naturally occurring element on Earth is
astatine.
18. In its purest form, gold is not a very reactive metal
and does not tarnish or corrode.
19. Sodium and potassium are highly reactive metals that
are stored under oil to prevent them from reacting with the air.
20. The element bismuth is denser than lead and is the
most naturally diamagnetic element (meaning it is repelled by magnetic fields).
