wHO INVENTED NEUTRONS IN AN ATOM?

Answer 1

James Chadwick invented the neutrons in an atom.

Answer 2

First of all,i would like to tell u that nobody invented but discovered it.hope,u know the difference between discovery&invention
Here's the answer
Following the discovery of the proton in 1919, British physicist Ernest Rutherford suggested that a third particle, in addition to the proton and the electron, existed inside the atom. In 1930 the German physicists Walther Bothe and Herbert Becker bombarded beryllium with alpha particles and produced a radiation that passed through ten centimeters of lead. In 1932 French physicists Irène and Frédéric Joliot-Curie found that this radiation could knock protons out of hydrogen atoms. In the same year, British physicist James Chadwick measured the energy of the protons emerging from the hydrogen atoms and showed that they had been knocked out by a particle of about the same mass, but electrically neutral. This new particle was therefore named the neutron

Answer 3

neutrons was invented by James Chadwick in the year 1932.

Answer 4

James Chadwick

hard to tell isn't it? I still go along with J Chadwick.

Edit: Incidentally I don't see any theological problem with J Chadwick 'inventing' the neutron - it's just an idea that neatly describes a set of observed behaviours.

Answer 6

In 1930 Walther Bothe and H. Becker in Germany found that if the very energetic alpha particles emitted from polonium fell on certain light elements, specifically beryllium, boron, or lithium, an unusually penetrating radiation was produced. At first this radiation was thought to be gamma radiation although it was more penetrating than any gamma rays known, and the details of experimental results were very difficult to interpret on this basis. The next important contribution was reported in 1932 by Irène Joliot-Curie and Frédéric Joliot in Paris. They showed that if this unknown radiation fell on paraffin or any other hydrogen-containing compound it ejected protons of very high energy. This was not in itself inconsistent with the assumed gamma ray nature of the new radiation, but detailed quantitative analysis of the data became increasingly difficult to reconcile with such a hypothesis. Finally (later in 1932) the physicist James Chadwick in England performed a series of experiments showing that the gamma ray hypothesis was untenable. He suggested that in fact the new radiation consisted of uncharged particles of approximately the mass of the proton, and he performed a series of experiments verifying his suggestion. Such uncharged particles were eventually called neutrons, apparently from the Latin root for neutral and the Greek ending -on (by imitation of electron and proton).

I hope it helps!

Answer 7

actually no man invented neutrons.it was James Chadwick who discovered it inside the atom.

Answer 8

God. NATURE. Neutrons were discovered by Chadwick. Not invented.

Answer 9

Nobody "invented" it; it was discovered by Sir James Chadwick in 1932

Answer 10

God invented the neutrons in an atom but JJ Thompson was the one who discovered it.
