Louis de Broglie was a French scientist who's hypothesis helped the present day theory of the atomic sturcture and won himself the Nobel Prize of Physics.
Usually, the weight of an atom would be about twice that of the atomic number. For example, Boron's atomic number is 5, and it has an atomic mass 0f 10.81 amu. This is because of the fact that a neutron and a proton both weight about 1 amu, and an electron is insignificant. To calculate the atomic weight to a higher accuracy than a mere estimate, is beyond me. I hope this helped.
Atomic number of oxygen: 8After the IUPAC Tables, 2009 the atomic weight of oxygen is[15,99903; 15,99977].The abridged conventional atomic weight is (also after the IUPAC Tables, 2009) 15,999; following the IUPAC tradition the correct expression is atomic weight, not atomic mass.
right..... im not sure about it but since the atomic mass of zinc is 65.39 amu then most probably it will be 65 amu rounded to the nearest whole number. hope that helped :D
That would Beryllium, with an atomic number of 4 and mass number of 9Hope this helped!
it helped it make atomic bombs and other nuclear weapon's.
You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
The atomic bomb helped peopole know more about radiation poisining and helped in the advancements in neuclear energy.
15 :) Hope this helped

Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.

A complex problem I helped solve was when my friend was arguing with a girl .
