Louis Nicolas Vauquelin
ATOMIC NUMBER YEAR IN WHICH IT WAS DISCOVERED? it was discovered in 1913 by British physicist Henry Mosely
Beryllium is a chemical element, with the symbol of Be, atomic number 4. It was discovered by Louis-Nicholas Vauquelin in 1798
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 atomic number for beryllium is 4.
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.
The atomic number of Beryllium is 4.
118 will be its atomic number.
The atomic number of unnilennium is 119. It is a hypothetical element that has not been discovered yet.
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 atomic number of the element with the symbol Be (Beryllium) is 4.
The element that has an atomic number of 43 is Technetium. It was discovered in 1937 and its symbol is Tc.
