What is the first man made element on the periodic table?

Answer 1

Chemical Element: technetium

(Modern Latin: from Greek, technetos, "artificial"; the first man-made artificial element; radioactive metal)
Chemical-Element InformationSymbol: Tc
Atomic number: 43
Year discovered: 1937

Discovered by: Emilio Gino Segré (1905-1989), an Italian physicist, and Carlo Perrier of Italy.

• Element 43 (technetium) was predicted on the basis of the Periodic Table by Mendeléyev.
• He suggested that it should be very similar to manganese and gave it the name eka-manganese.
• Technetium was erroneously reported as having been discovered in 1925, at which time it was named masurium.
• The element was actually discovered by C. Perrier and Emilio Gino Segrè in Italy in 1937.
• It was found in a sample of molybdenum bombarded by deuterons.
• Technetium was the first element to be produced artificially and all its isotopes are radioactive.
• It is named after the Greek word technetos, meaning "artificial".

Answer 2

Although Technetium has the lowest atomic number out of all the man-made elements, I think the first was actually Neptunium

Answer 3

The first manmade element was technetium because scientists failed to find it naturally

Answer 4

Technetium (Tc) was the first man made element. With atomic number 43 it is the lowest chemical element without a stable isotope.

Answer 5

If you are looking at the proper periodic table, there aren't any man made elements.

Answer 6

The first man-made element on the periodic table is technetium, with atomic number 43. It was first synthesized in a laboratory in 1937.

Answer 7

technetium - Tc

Answer 8

Technetium
