Hello classmates, today I am gonna write about Dmitri Ivanovich Mendeleyev who was a Russian chemist, traveler, photographer, collector and an important person for the chemistry. He was born on February 8th, 1834 and died on February 2nd, 1907, at the age of 72 years because of pneumonia. He studied in San Petersburg University and years later, was a teacher of technology and chemistry in the same university.
His greatest discovery was the pattern, in what is now known as the periodic table of the elements, an invention of great utility in the sciences, especially in chemistry and physics, the elements are grouped according to their atomic weights and valences. In addition, he intuited that there were still elements to be discovered and for this reason, there were gaps in the table, he pointed out the properties they should have.
I admire this person because he contributed to a great development in the sciences, facilitating the study of chemistry for the people and giving way to others, discovered more elements.

the great mother Russia
ResponderEliminarI remember that in my school, my physics teacher talk us about him
ResponderEliminarI didnt know him!
ResponderEliminarMendeleyev was a nice sciencist, hope to be like him someday
