Health benefits of eating Corn

Corn is native to America. Every part of this unique product is used. Corn is a very useful product. It contains amino acids, vitamins E, B group, K, PP, almost all of the Mendeleev table. That is why corn has many benefits for human health.

5 Accidental Discoveries That Changed the History of Humankind

It is a well-known fact that Mendeleev saw in the dreams the periodic table of his elements. However, it is worth noting that he worked on this project for many years, so his dream seemed like a logical conclusion. However, some of the great discoveries that changed the history of the world happened by accident. We have compiled a list of "random" inventions that have made our reality completely different. 1.

How to find the group number, periodic number and block of an element in Chemistry

In previous times it was difficult to know the group, block and period of the elements in the periodic table after the elements were placed into their various groups and positions in the periodic table by Mendeleev. Mendeleev didn't actually understand everything on his table, but it was in a dream that all the elements were being arranged and placed in a table with their appropriate groupings. People wanted to find out some specific details about the elements in the table, then the configurations were evolved.

SCANDIUM: Fifth Most Expensive Element

Discovery Lars Fredrik Nilson and his team detected this element in the minerals euxenite and gadolinite in 1879. Nilson prepared 2 grams of scandium oxide of high purity. He named the element scandium from the Latin Scandia meaning Scandinavia. Nilson was apparently unaware of Mendeleev's predictions, but Per Teodor Cleve recognised the correspondence and notified Mendeleev, which predicted the existence of an element ekaboron with an atomic mass between 40-48 in 1869.

ASTATINE: The Only Radioactive Halogen

Astatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time. Mendeleev named this unknown element eka-iodine due To it's position directly below iodine in the halogen group of elements. It is highly radioactive. It belongs to group 7. It is the heaviest known halogen. It can only be found on Earth following the decay of thorium and uranium. It was discovered by Dale R. Corson, Kenneth Ross Mackenzie, Emilio Segrē. The name came from the Greek 'astato
