In 1904, British physicist J.

J Thomson and other people shown that cathode rays (electrons) were being existing in all issue. collier anti aboiement sur homme 1collierfrance5677 Thomson proposed that the atom was a sphere of good demand in which embedded had been rings of detrimental costs (electrons) , like «plums in a pudding». collier homme grec 1collierfrance5211 Lather on, in 19 century, the discoveries of radiation sales opportunities to a new development of Physics.

We realized that specific aspects emitting radiation, this suggested that atoms are no for a longer period indivisible and not indestructible, as proposed in Dalton’s atomic design. Radiation offers an critical instrument for the research of issue. collier prenom gabriel In 1911, Rutherford to start with recommended the use of alpha particles to probe the inner framework of the atom. collier perle y 2collierfrance7350 At last, the nucleus and its protons have been discovered.
