Today we introduce you about a New Zealand man who won the Nobel Prize in chemistry in 1908 and then he performed his most famous work and found in the atom. Encyclopaedia Britannica considers him to be the greatest since . That great New Zealand man is our "scientist of the day" today. (2nd article of the day)

It's death anniversary of (1st Baron Rutherford of Nelson), the father of nuclear physics --

(Scientist of the Day - 19 October)

In early work, Rutherford discovered the concept of , the radioactive element and differentiated and named and radiation. This work is the basis for the in he was awarded in 1908 "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances".

Rutherford performed his most famous work after he became a Nobel laureate. In 1911, although he could not prove that it was positive or negative, he theorized that atoms have their concentrated in a very small and thereby pioneered the Rutherford model of the atom, through his discovery and interpretation of Rutherford scattering by the (look the shown image) of and .

He performed the first induced in 1917 in experiments where nuclei were bombarded with alpha particles. As a result, he discovered the emission of a subatomic particle which, in 1919, he called the "hydrogen atom" but, in 1920, he more accurately named the .

Under his leadership the was discovered by in 1932 and in the same year the first experiment to the nucleus in a fully controlled manner was performed by students working under his direction, and .

After his death in 1937, he was buried in Westminster Abbey near Sir . The chemical element (atomic number 104) was named after him in 1997.
