ATOMIC NUMBER YEAR IN WHICH IT WAS DISCOVERED? it was discovered in 1913 by British physicist Henry Mosely
Henry Gwyn-Jeffreys Moseley in the 1910s.
the atomic bomb was not discovered, it was invented then built.
He was attempting to do just that- make an atomic bomb.
well who is it

Neodymium, with the chemical symbol Nd, is the chemical element with the atomic number 60.
The atomic number for Manganese is 25. It was discovered in 1774 so was one of the earlier elements discovered. It has a melting point of 1519 Kelvin.
The concept of atomic number was discovered by the scientist Henry Moseley in 1913. He found that the number of protons in an atom's nucleus determines its identity, which led to the organization of the periodic table based on atomic number.
m.g mosly found the number of protons an atom has. So he is the person discovered atomic number.
60
60 protons, as its atomic number is 60.
118 will be its atomic number.
The atomic number of unnilennium is 119. It is a hypothetical element that has not been discovered yet.
Palladium has 60 neutrons. It has an atomic number of 46, which means it has 46 protons. To find the number of neutrons, you subtract the atomic number (protons) from the atomic mass (protons + neutrons). Palladium's atomic mass is approximately 106.4, so 106.4 - 46 = 60 neutrons.
The atomic number was not discovered, as such. It's only when scientists realised that there were such things as atoms and the weights of them varied that they put them into some sort of order. So the lightest (hydrogen) is atomic number 1 and the next (helium) is 2, and so on.
The element that has an atomic number of 43 is Technetium. It was discovered in 1937 and its symbol is Tc.
