July 10, 2016 Sunday

Today I drove to the gym and did squats after 3 weeks

Both the quadriceps and the knee joint felt very weak


Was unable to go down low below the knee level



As you see, the notion or the definition of the element was not rather loose.

So how did the link between atomic number and the definition of element get established?

Perhaps we can attribute 3 men to establish this crucial link.

They all came from different countries:

1. Jons Jacob Berzelius in early 1800s hailed from Sweden

2. Dmitri Ivanovich Mendeleev in late 1800s from the Russian Empire

3. Henry Moseley in early 1900s an Englishman

Berzelius had lost both his parents at an early age.

Under the care of his relatives, he did his studies to become a medical doctor in 1802 from the Uppsala University (ranks 60 among the World Universities).

Oddly enough, from his career as a physician, he started to devote more time on physical chemistry.

He began to determine atomic weights of elements thereby on the way established the principles of stoichiometry.

In essence, he had founded the law of conservation of mass in a chemical reaction.

This essentially meant that the total mass of the reactants had to be equal to the total mass of the products if no energy was lost as heat or light.

Example:
CH4 + 2O2 ~ CO2 + 2H2O
(Sorry for my inability to write numbers in subscript).

This is an extremely powerful idea from which a lot else automatically follows if taken to its complete logical end.

Berzelius, to aid his experiments, developed a system of alphabetical notation for the elements such as O for oxygen, Fe for iron with numbers to show their proportions.

We still use them today.

Yet we have never heard of this great doctor and chemist called Berzelius.

What hope does an average ape has of being remembered after his disorganization of atomic arrangement?

None!

Good night mon ami and my fellow cousin ape.
